Abstract

The randomized clinical trial (RCT) is one of the most powerful tools for the obtainment of evidence for healthcare. Despite some possible variations, they are based on the comparison between two or more interventions, which are controlled by researchers and randomly applied on a group of participants. The aim of this study was to describe aspects of external and internal validity of RCTs, as well as to present  databases for their obtainment and quality assessment tools.
