The journal *Archivos de Medicina* (Manizales) adheres to the four criteria proposed by the ICMJE for a person to be considered an author, as follows:
All authors must meet all four criteria, and all those who meet the criteria must be listed as authors. The order of authorship must be approved by all authors before the manuscript is submitted for publication. Any person who participated in the work but does not meet all four criteria should be acknowledged in the acknowledgments section.
