This Journal is a member of the Committee on Publication Ethics
This Journal recommends that authors follow the Uniform Requirements for Manuscripts Submitted to Biomedical Journals formulated by the International Committee of Medical Journal Editors (ICMJE)
There are no fees payable to submit or publish in this journal.
Please read the guidelines below then visit the Journal’s submission site http://mc.manuscriptcentral.com/td to upload your manuscript. Please note that manuscripts not conforming to these guidelines may be returned.
Only manuscripts of sufficient quality that meet the aims and scope of Tropical Doctor will be reviewed.
As part of the submission process you will be required to warrant that you are submitting your original work, that you have the rights in the work, that you are submitting the work for first publication in the Journal and that it is not being considered for publication elsewhere and has not already been published elsewhere, and that you have obtained and can supply all necessary permissions for the reproduction of any copyright works not owned by you.
The purpose of the journal is: (1) to publish contributions on the prevention, management and treatment of prevalent diseases, and on the promotion of health in developing countries; and (2) to present a picture of the problems of health and disease in these countries as a step towards lessening the sense of isolation felt by those working far from advanced medical centres. The editors will provide support for authors whose first language is not English. No paper will be rejected merely on the basis of a lack of familiarity with the style of written English language. We prefer UK English usage, metric values, and laboratory results in SI units. Prior to the use of abbreviations, a term must be written in full, e.g. Millennium Development Goals (MDG).
From 1000-3000 words. The content of the paper must justify its length. For reports of original investigative work, traditional division into sections is required: abstract (maximum 150 words), introduction, patients/methods, results, discussion, acknowledgements, references. Black and white photographs and line drawings are welcomed if they illuminate the text.
Up to 1000 words, with a maximum of two tables or figures and 10 references. A brief, three sentence summary should be included. The majority of papers accepted for publication are Short Reports.
For original research work. Up to 700 words with a single table or figure and a maximum of five references.
Up to 600 words (one page of Tropical Doctor ). A brief summary should be included. The contents should be logically ordered, but division into sections is optional. One table or figure is allowed in addition to text. Up to five references may be given. Suitable for presenting descriptive studies (a series of cases of . . .etc.), some field studies, personal experience or individual case reports of particular interest.
Welcomed on any subject, including editorials or articles that have appeared in Tropical Doctor. Suitable for voicing opinions, which need not be orthodox. Letters may also be a suitable vehicle for presenting items of experience or observation that are too brief for Short Reports.
Methods and Devices
Papers describing procedures, techniques or equipment adapted by readers to their own conditions of work are welcomed. The author's name, qualifications, position, and place of work should be given. Illustrations, either clear black and white drawings or black and white photographic prints with good contrast, can be considered. References should be kept to a minimum.
All papers submitted for publication undergo peer review.
The covering letter is important. To help the Editors in their preliminary evaluation, please indicate why you think the paper suitable for publication. If your paper should be considered for fast-track publication, please explain why.
Manuscripts are accepted for review with the understanding that the same work has not been submitted or published elsewhere and, if accepted by Tropical Doctor, will not be submitted or published elsewhere. If evidence of dual submission is found, the manuscript will be rejected or, if published, retracted.
Unnecessary subdivision of a study into several manuscripts is not acceptable. If any material published previously is included, for clarity or other reasons, this should be indicated with appropriate citation in the manuscript. One copy of any material that might be regarded as "duplicate publication," such as preliminary reports (including reviews, symposia and proceedings) or other publications (submitted, in press or published) containing data or other material included in the submitted manuscript, must be sent to the Editor when the manuscript is submitted. Clearly label such material so as to avoid any confusion with the submitted manuscript. Normally it is regarded as acceptable to include in a detailed journal article material that has been presented previously in summary form in reviews, symposia, or conferences, provided appropriate citation is included.
As part of the submission process you will be asked to provide the names of X peers who could be called upon to review your manuscript. Recommended reviewers should be experts in their fields and should be able to provide an objective assessment of the manuscript. Please be aware of any conflicts of interest when recommending reviewers. Examples of conflicts of interest include (but are not limited to) the below:
- The reviewer should have no prior knowledge of your submission
- The reviewer should not have recently collaborated with any of the authors
- Reviewer nominees from the same institution as any of the authors are not permitted
Please note that the Editors are not obliged to invite any recommended/opposed reviewers to assess your manuscript.
Papers should only be submitted for consideration once consent is given by all contributing authors. Those submitting papers should carefully check that all those whose work contributed to the paper are acknowledged as contributing authors.
The list of authors should include all those who can legitimately claim authorship. This is all those who:
- Made a substantial contribution to the concept and design, acquisition of data or analysis and interpretation of data,
- Drafted the article or revised it critically for important intellectual content,
- Approved the version to be published.
Authors should meet the conditions of all of the points above. Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content.
When a large, multicentre group has conducted the work, the group should identify the individuals who accept direct responsibility for the manuscript. These individuals should fully meet the criteria for authorship.
Acquisition of funding, collection of data, or general supervision of the research group alone does not constitute authorship, although all contributors who do not meet the criteria for authorship should be listed in the Acknowledgments section. Please refer to the International Committee of Medical Journal Editors (ICMJE) authorship guidelines for more information on authorship.
All contributors who do not meet the criteria for authorship should be listed in an Acknowledgements section. Examples of those who might be acknowledged include a person who provided purely technical help, or a department chair who provided only general support.
2.3.1 Writing Assistance
Individuals who provided writing assistance, e.g. from a specialist communciations company, do not qualify as authors and so should be included in the Acknowledgements section. Authors must disclose any writing assistance – including the individual’s name, company and level of input – and identify the entity that paid for this assistance.
It is not necessary to disclose use of language polishing services.
Any acknowledgements should appear first at the end of your article prior to your Declaration of Conflicting Interests (if applicable), any notes and your References.
Tropical Doctor requires all authors to acknowledge their funding in a consistent fashion under a separate heading. Please visit the Funding Acknowledgements page on the SAGE Journal Author Gateway to confirm the format of the acknowledgment text in the event of funding, or state that: This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.
It is the policy of Tropical Doctor to require a declaration of conflicting interests from all authors enabling a statement to be carried within the paginated pages of all published articles.
Please ensure that a ‘Declaration of Conflicting Interests’ statement is included at the end of your manuscript, after any acknowledgements and prior to the references. If no conflict exists, please state that ‘The Author(s) declare(s) that there is no conflict of interest’.
For guidance on conflict of interest statements, please see the ICMJE recommendations here
Medical research involving human subjects must be conducted according to the World Medical Association Declaration of Helsinki
Submitted manuscripts should conform to the ICMJE Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals, and all papers reporting animal and/or human studies must state in the methods section that the relevant Ethics Committee or Institutional Review Board provided (or waived) approval. Please ensure that you have provided the full name and institution of the review committee, in addition to the approval number.
For research articles, authors are also required to state in the methods section whether participants provided informed consent and whether the consent was written or verbal.
Information on informed consent to report individual cases or case series should be included in the manuscript text. A statement is required regarding whether written informed consent for patient information and images to be published was provided by the patient(s) or a legally authorized representative.
Please also refer to the ICMJE Recommendations for the Protection of Research Participants
All research involving animals submitted for publication must be approved by an ethics committee with oversight of the facility in which the studies were conducted.
Tropical Doctor conforms to the ICMJE requirement that clinical trials are registered in a WHO-approved public trials registry at or before the time of first patient enrolment as a condition of consideration for publication. The trial registry name and URL, and registration number must be included at the end of the abstract.]
The relevant EQUATOR Network reporting guidelines should be followed depending on the type of study. For example, all randomized controlled trials submitted for publication should include a completed Consolidated Standards of Reporting Trials (CONSORT) flow chart as a cited figure, and a completed CONSORT checklist as a supplementary file.

Tropical Doctor conforms to the SAGE house style. Click here to review guidelines on SAGE UK House Style.
Manuscripts must be submitted using double line-spaced, unjustified text throughout, with headings and subheadings in bold case. Press ‘Enter’ only at the end of a paragraph, list entry or heading.
The first page should contain the full title of the manuscript, a short title, the author(s) name(s) and affiliation(s), and the name, postal and email addresses of the author for correspondence, as well as a full list of declarations. Please also include a list of up to five keywords.
The title should be concise and informative, accurately indicating the content of the article. The short title should be no more than six words long.
A summary of no more than 250 words must accompany all Review Articles, Original Articles and Short Reports, Research Letters, Case Reports, and Methods and Devices. The summary should cover: Background (context and rationale); Methods (type of study, patients, materials, techniques); Results (main numerical data and statistical information); and Conclusions (main objective and verifiable conclusions). Correspondence pieces do not require a summary.
Tables must be prepared using the Table feature of the word processor. Tables should not duplicate information given in the text, should be numbered in the order in which they are mentioned in the text, and should be given a brief title.
All figures should be numbered in the order in which they are mentioned in the text. All figures must be accompanied by a figure legend. If figures are supplied in separate files, the figure legends must all be listed at the end of the main text file.
Line drawings should be produced electronically and clearly labelled using a sans serif font such as Arial. Graphs may be supplied as Excel spreadsheets (one per sheet). Other line drawings should be supplied in a suitable vector graphic file format (e.g. .eps)
All photographic images should be submitted in camera-ready form (i.e. with all extraneous areas removed), and where necessary, magnification should be shown using a scale marker. Photographic images must be supplied at high resolution, preferably 600 dpi. Images supplied at less than 300 dpi are unsuitable for print and will delay publication. The preferred file format is .tif.
Symbols and abbreviations should be those currently in use. Authors should not create new abbreviations and acronyms. Prior to the use of abbreviations, a term must be written in full, e.g. Millennium Development Goals (MDG).
All measurements should be expressed in SI units.
If preparing statistical data for publication, please read the statistical guidelines.
These guidelines are designed to help authors prepare statistical data for publication and are not a substitute for the detailed guidance required to design a study or perform a statistical analysis. Each section of a scientific paper is addressed separately.
The number and source of data must be stated and conclusions which have a statistical basis must be substantiated by inclusion of pertinent descriptive statistics (mean or median, standard deviation [SD] or interquartile range, percentage coefficient of variation [%CV], 95% confidence limits, regression equations, etc.).
Experimental design, subject selection and randomization procedures should be described and analytical precision quoted when appropriate. The hypotheses to be tested by a statistical procedure must be stated and where appropriate power calculations for the sample size used should be given (it is recommended that the power is X80%). In case-control studies clearly define how cases and controls were selected and what matching has taken place.
We would advise authors to consider the STARD,1 CONSORT2 and STROBE3 statements for studies reporting diagnostic or clinical trials. They offer guidance on writing reports with complete clarity.
Unnecessary precision, particularly in tables, should be avoided. Rounded figures are easier to compare and extra decimal places are rarely important. Descriptive statistics require an additional digit to those used for the raw data. Percentages should not be expressed to more than one decimal place and not be used at all for small samples.
Normally distributed data should be described using a mean, SD and/or %CV and expressed as ‘mean (SD)’ not ‘mean ± SD’. When data are not normally distributed, following demonstration by tests such as the Shapiro-Wilk test,4 then medians and interquartile ranges should be used in place of mean and SD. Skewed data can often be normalized by logarithmic transformation or a power transformation. The statistical analysis and calculation of summary statistics should be carried out on the transformed data and the summary statistics transformed back to the original scale for presentation. If a logarithmic scale is used then graphs should display non-transformed data on a logarithmic scale.
Graphs showing data of comparable magnitude should be of a similar size and design. All individual points should be displayed where possible by displacing overlapping points. Error bars showing the standard error of the mean (SEM) or interquartile range, as appropriate, can be used to aid interpretation of the data.
The results of significance tests such as Student’s and chi-squared should be presented with descriptive statistics, degrees of freedom (if appropriate) and probability P. The validity of any assumptions should be checked (e.g. conventional t-tests assume a normal distribution and equal variance for each set of data). For 2 x 2 contingency table analysis by the chi-squared test the continuity correction must be applied and for small expected frequencies Fisher’s Exact Test used. P values should be reported in fullto1or 2 significant figures, describing P values as 40.05 or NS (not significant) should be avoided. If the results are highly significant and the calculated P value from the computer is e.g. 0.000, then the use of P <_0.0005 is="is" acceptable.="acceptable." confidence="confidence" intervals="intervals" should="should" be="be" stated="stated" particularly="particularly" for="for" non-significant="non-significant" results.="results." br="br">The conventional use of statistical significance is P≤0.05. If a different significance level needs to be used then the reasons why must be clearly stated in the statistical method section.
Statistical significance should not be equated to importance and P values should not be compared between different data sets or different statistical tests. Association should not be interpreted as causation without additional evidence.
Multiple comparisons can produce spurious and misleading significance values. The primary hypothesis should always be clearly stated, and associations detected by retrospective analysis should be interpreted with caution. Whenever possible a single overall statistical test should be applied first e.g. ANOVA. If this is not significant then multiple comparisons must not be applied. If it is significant then some form of multiple range test can be applied. If a single overall test is not possible then multiple comparisons must use a Bonferroni type significance level.
With paired data the differences between individual pairs of data and the variability of the differences are more important than the individual values. Graphical representation should also show the difference between individual pairs, e.g. by plotted lines joining the paired data points.
Standard regression analysis
Standard regression analysis requires data points to be independent (repeated measurements are not independent). The independent variable should be measured without significant error, e.g. age or time, and the points should be evenly distributed over the range and have no outliers (this can be easily examined with a scatterplot). These requirements are rarely satisfied with biological data.
Method comparison using regression and correlation coefficients is inappropriate and should be performed using Altman and Bland difference plots.5 If a standard scatter plot and regression line are thought to be useful they can be given along with the Altman–Bland plot. Remember if two methods are supposed to be measuring the same thing then it is extremely likely they will be correlated so as a statistical tool correlation is not going to tell you anything new.
If you are carrying out complicated statistical analyses e.g. multivariate analysis, ROC analysis etc., then it is recommended that you seek advice from a statistician.
