3.2. Summary: summarize, in no more than 200 words, the purpose of the study or research, the materials and methods that were used, the main results obtained and the most important conclusions, with its respective Spanish version. Similarly, use the structured summary model and don’t use non-standard abbreviations.

Authors will propose 3-6 “keywords”, which must be found in the list of MeSH descriptors, in English, and DeCS descriptors, in Spanish, available at and accessible, respectively.

Materials and Methods: In this sections authors have to describe how the studied subjects were selected: whether they were patients or experimental animals, organs, tissues, cells, etc., and their respective controls. Authors must also identify the methods, instruments or devices and the procedures that were used with an appropriate accuracy so it is possible for other observers to reproduce the results. If well-established and frequently used methods (including statistical methods) were used, authors only have to mention them and cite the respective references. On the contrary, when the methods have been published but are not well known, authors must provide the respective references and give a brief description. If the methods are new or innovative or the authors have implemented some changes to established methods, these changes must be precisely, their usage justified and their limitations stated.

If the authors, in the making of the article, have performed experiments on human beings, there must be an explicit statement informing if the procedures carried out abode by consistent ethical standards of the Declaration of Helsinki (updated in 2013) and if they were reviewed and approved by an ad hoc committee of the institution where the study was conducted.
