3 Abstract and key words – The second page must contain abstracts in Portuguese and English (maximum 250 words). The abstract must be written in a single precise and concise paragraph; its content must follow the formal structure of the text, that is, objective, basic procedures, most important findings and conclusion. Abstracts must be followed by up to five key words. It is suggested the consultation to MeSH - Medical Subject Headings - of Medline (www.nlm.nih.gov/mesh/ meshhome.html) and to the DeCS – Descritores em Ciências da Saúde – of the health virtual library of LILACS (http://decs.bvs.br).
4 Structure – It is suggested to organize the texts according to the following formal structure: a) Introduction, state the purpose of the article, justifying the relevance of the study in view of pertinent literature findings; b) Methodology, detail sample selection, procedures and materials applied, in such a way that allow other researchers to reproduce the results, as well as the statistical methods used in data analysis (avoid sole reliance on statistical hypothesis testing, such as the use of P values, which fail to convey important quantitative information); c) Results, make a concise factual exposition of the observation, in logical sequence, with the support of graphs and tables as it is fit, taking the double care not to refer readers solely to the latter neither to repeat in the text every datum on the tables; d) Discussion, comment most important findings, discussing the results achieved and comparing them to previous studies results; e) Conclusion, summarize logic inferences grounded on the Results and Discussion sections.
5 Tables, graphs, figures, diagrams – are considered graphic elements. Only manuscripts containing up to five graphic elements will be considered for review. Authors should carefully select them for their relevance. Graphs are justifiable only to allow quick apprehension of complex variable behavior, and not to illustrate, for instance, differences between two variables. The text must present indications of the ideal insertion of the graphic elements, which should only be present in full at the end of the text. Tables (title in the upper part) must be typed in the text processor and numbered (in Arabic numerals) in the order of citation in the text; in Portuguese, decimals are separated by comma; full extent of abbreviations must be given in footnotes.
Figures, graphs, photographs and diagrams (title at the bottom) must be equally numbered (in Arabic numerals) in the order of citation. Abbreviations and further information are given in footnotes following the title.
6 References – References must be organized in numerical sequence, according to the order in which they were cited in the text for the first time, following the Uniform Requirements for Manuscripts Submitted to Biomedical Journals by the International Committee of Medical Journal Editors – ICMJE http://www.icmje.org/index.html.
