Which type of evidence is considered to occupy the highest position?
The reason that studies are placed into a hierarchy is that those at the top are considered the “best evidence”. In the case of therapeutic trials this is the randomized controlled trial (RCT) and meta-analyses of RCTs. RCTs have within them, by the nature of randomization, an ability to help control bias.
