Crossmark policy

The journal *Archivos de Medicina* adheres to the Crossmark policy, which aims to inform readers of the status of an article and its metadata. Crossmark notifies readers of any changes made to an article (updates, corrections, retractions, etc.). The Crossmark button allows readers to be certain that they are viewing the most recent version of the document and that it is citable. 

Thus, Crossmark is a Crossref initiative that allows users to formally locate the most up-to-date version of a scientific publication.
