Using Evidence Hierarchies to Find the Best Evidence: A Procrustean Bed?

Topics include how hierarchies could be detrimental in promoting EBP, the story of the Procrustean bed of Greek innkeeper Procrustes, and the evidence pyramid of randomized controlled trials (RCT), case reports and case-control studies.
