The norms below must be followed for all types of works, and are based on the format proposed by the International Committee of Medical Journal Editors (ICMJE), published in the article Uniform requirements for manuscripts submitted to biomedical journals, available at http://www.icmje.org/recommendations/browse/manuscript-preparation.
The authors must submit the articles containing:
- Text typed in double-spaced 12 point Arial font, 2.5cm margin on each side, highlighting each section of the article.
- Permission for reproduction of material and transfer of copyright form (available at the electronic submission system).

- Conflict of interest disclosure statement of each author (available at the electronic submission system).
Preparing a manuscript
Title of the article, in Portuguese and English, which should be concise but informative.
Abstract, in Portuguese and English, with a maximum of 250 words. For original articles, the abstracts should be structured (Objective, Methods, Results, Conclusion), describing the main parts of the work and highlighting the most relevant data. For articles of other sections, the abstract should not be structured.
Specify at least 5 and at most 10 keywords, in Portuguese and English, which reflect the content of the paper. The keywords must be based on the Health Sciences Descriptors (DeCS) published by Bireme, and translated from the Medical Subject Headings (MeSH) of the National Library of Medicine, and available at: http://decs.bvs.br.
Registry in Clinical Trials Database
Indicate, for Clinical Trials, the registry number in the clinical trials database (https://clinicaltrials.gov).*
* Important note: in support of the policies on registry of clinical trials of the World Health Organization (WHO) and ICMJE, the journal einstein (São Paulo) understands the relevance of these initiatives for registration and international dissemination of information on clinical studies. It only accepts for publication the clinical research articles that have received an identification number in one of the Clinical Trials Registries validated by the criteria established by the WHO and the ICMJE, available at https://clinicaltrials.gov or at the website PubMed, in the item <clinicaltrials.gov>. The identification number should be shown at the end of the abstract.
It must comply with the structure required for each category of article. Citations of authors in the text must be numbered sequentially, by superscript Arabic numerals in parentheses, in all article categories. The full terms for which the abbreviations and acronyms stand for should precede their first use in the text. Do not use abbreviations or acronyms in title and abstract. In table and figure legends, the abbreviations must be followed by the full term.
They describe collaboration by individuals that deserve acknowledging but do not justify authorship. Please include acknowledgements for financial and/or technical support, etc.
They must be numbered consecutively in the same order they appear in the text, and identified by Arabic numerals. References follow the “Vancouver Style”, and the titles of journals should be abbreviated according to the style presented by the List of Journals Indexed in Index Medicus, of the National Library of Medicine, available at http://www.ncbi.nlm.nih.gov/nlmcatalog/journals. For any references, mention up to six authors. In case of more than six authors, mention the first six, followed by et al., as shown in the following examples:
