The selection of articles for each issue of a previously selected journal should include the following items:

• Reports of original articles, with a signed title and stated authorship.
• Review articles, updates, and case reports.
• Comments or discussions on subjects or original articles with identified authorship and/or titles. If the discussion does not specify authorship, it will be considered part of an article, and its pagination will be included with that of the article.
• Editorials that can be regarded as special articles; they typically include a bibliography.
• Scientific papers presented at events and published in journals. If only abstracts are published, it is not necessary to analyze each abstract separately; the issue should be considered as a whole and indexed by the specific subject of the event.
• Letters to the Editor of unusual significance, equivalent to a brief article.
• Scientifically significant interviews.
• Anatomo-clinical case meetings.
• Obituaries, including significant biographical data.
• Clinical trials duly registered in databases.

Do not consider:

• Editorials, typically signed by the editor and addressing points related to the recurring issue.
• News articles.
• Translations or reprints.
• Reproductions of articles already published in national and international journals, except in cases mentioned in the ICMJE recommendation – item III.D.3.
• Editorials, letters, interviews, and dialogues without significant scientific value or of a personal nature.
• Abstracts in general: articles, books, scientific event papers, etc.
• Book reviews.
• Drug and equipment advertisements.
• Administrative or informative reports on scientific events (Conference, Congress, Seminar, etc.).
• Financial and administrative reports.
