The excellence of the articles published in a scientific Journal depends on a careful review and selection of the submitted material by both the referees and the Journal's editorial board. In this regard, two steps of the editorial process are fundamental in ensuring the quality of the material offered: 1) the selection of the best papers from the total number of articles submitted and 2) improving their content and presentation. These two strategic elements are entrusted by the referee's team invited by the editorial committee. For Revista Ciencia e Innovación en Salud (RevCIS) it is a pleasure to support the work of the reviewers both from the direction and from the editorial committee to offer them academic accompaniment, administrative support and recognition of their work. At RevCIS, we are aware that improving the quality of reviews is improving the quality of the Journal. We are aware that the experts reviewing process is a costly task in terms of time and dedication, yet it is precious in the development of science and consequently in the advancement of knowledge of humanity.

The reviewers' work is of great help to the academic and research ecosystem: The undergraduate and graduate students, the researchers, the authors, the administrative actors of the National System of Science and Technology and the editors, who are ultimately responsible for perfecting, as a craftsman polishing a Jewel, the article that is finally published. The peer-review process is thus a central task in an indexed biomedical journal such as ours. 

On the other hand, one of the missions of the editorial management is to ensure that the review is not inbred, i.e. that the refereeing is not done by people very close to the authors applying for an article. For this reason, in  RevCIS , we request help from peer reviewers who - as far as possible - come from countries other than the authors' country of origin. In this vein, we want to avoid favouritism or discrimination towards the material being evaluated, and to offer a different view of the manuscript's content from the logics, methodologies, hermeneutic and epistemological horizons of the researchers from other latitudes, since what seems to be very important in one country is not always interesting for readers from other countries. Due to this strategy, foreign peer reviewers provide us with a cosmopolitan perspective of the object of study that is invaluable to us.

For these reasons, we firmly believe that reviewers are one of the essential links in the community we have been building around RevCIS.  We want to thanks the referee effort in our Journal dedicating precious hours without demanding any remuneration. 

This year, a total of 220 reviewers were invited by the editorial board, of which 150 (68.18%) investigators accepted the responsibility of reviewing an article. Our Journal received 145 articles during 2020 for publication, 40 have been published, of whom 22 have been rejected, two were withdrawn by the authors and 106 are still the editorial process. It is important to note that the average time invested by referees for its critical review was 69 days.

By virtue of the above, we would like to thank the following researchers for their selfless scientific work in the following Letter of Thanks
