As referred in the Uniform Requirements for manuscripts Submitted to Biomedical Journals, the authorship should be based on substantial contribution to:

1) conception and design of the study, or acquisition of data, or analysis and interpretation of data;

2) drafting the article or revising it critically for intellectual content;

3) final approval of the version to be published.

Acquisition of funding, collection of data or general supervision of the research group, alone, does not justify authorship.

The contribution of each author must be specified in the cover letter.

This information will be published.

Example: José Silva conceived the study and supervised all aspects of its implementation. António Silva helped in the conception of the study and analysed the data. Manuel Silva collected data and helped in its analysis. All authors contributed to the interpretation of the results and to the revision of the manuscript drafts.

In the case of the manuscripts signed by more than 6 authors, a reason must be given to justify such an expanded authorship.

All authors must approve, by written, any modification of the article authorship after its submission.

4) analysis of data.

The ethical considerations must be made at the end of this section.

Analysis of data

Describe the statistical methods with enough detail to allow other workers to reproduce the results.

When possible, quantify findings and present them with appropriate indicators of measurement error or uncertainty, such as confidence intervals. Avoid relying solely on statistical hypothesis testing, such as the use of P values, which fails to convey important quantative information.

Specify the computer software used.

Ethical considerations and informed consent

When reporting experiments on human subjects, authors should indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee and with the Helsinki Declaration by the World Medical Association (www.wma.net).

This approval and the acquisition of the informed consent must be mentioned in the methods section.


Present the results in logical sequence in the text, tables and illustrations.

Do not repeat in the text all the data in the tables or illustrations. Summarize only important observations.

Graphics should only be presented to improve the understanding of the results, regardless of the limited number of illustrations established for each type of article.

Presentation of numeric data

The numeric accuracy used on the presentation of the results should not be superior to the one allowed by the evaluation instruments.

To quantitative variables the presented measurements should not have more than one decimal part than the raw data.

Proportions must be presented with just one decimal part and small samples should not have decimals.

The testing statistics values, such as t or ?2, and the coefficients of correlation must be presented with no more than two decimals parts.

The P values must be presented with one or two significant figures, never on the form of P=NS, P<0.05 or P>0.05 in so far as the P value information could be important. When the P value is too small (inferior to 0.0001) it can be presented like P<0.0001.

Tables and Illustrations

Tables must appear after the references. Illustrations must appear after the tables.

All tables and illustrations should be cited in the text, numbered (separate Arabic numerals for tables and illustrations) consecutively in the order of their first citation.

Each table or illustration must have a brief title and footnotes (for example, abbreviations definitions) in order to be understood and interpreted without having to consult the text of the manuscript.

For footnotes or illustrations use the following symbols, in this sequence:

*, †, ‡, §, ||,¶, **, ††, ‡‡

Each table or illustration must be presented in separate pages with the respective title and footnotes.

For the tables use only horizontal lines.

Illustrations, including graphics, maps, photographs or other materials must be computerised or professionally drawn.

Illustrations must have legends.

Symbols, arrows or letters should contrast with the background.

The dimension of the illustrations is usually reduced to the width of a column, assuring that when reduced to publication each item will still be legible.

On the first submission of the manuscript, send copies of the photographs, illustrations or other materials such as x-ray films. Illustrations made on the computer or converted into electronic format after digitization must be inserted on the manuscript file.

Since the final print will be on black-and-white or grey, graphics should not be coloured. Three-dimensional graphics will only be accepted in special situations.

The resolution of black-and-white images must be at least 1200dpi and grey or coloured images must be at least 300dpi.

Legends, symbols, arrows or letters must be inserted in the photographs or illustrations image file.

The publication of illustrations in colour will be paid by the author.

When the manuscript is accepted, the illustrations will be asked in the most suitable format for the production of the journal.


Do not repeat in detail data given in the Results section, but discuss the limitations of the study and compare the results with other relevant studies. Emphasize the new and important aspects of the study and the conclusions that follow from them.

Link the conclusions with the goals of the study but avoid unqualified statements and conclusions not adequately supported by the data.


References should be listed after the main text, numbered consecutively in the order in which they are first mentioned in the text. The references numbers must be identified in parentheses. References must not be automatically numbered.
