“Randomized controlled trials, long regarded as the ‘gold standard’ of evidence, have been put on an undeserved pedestal. Their appearance at the top of ‘hierarchies’ of evidence is inappropriate; and hierarchies,themselves, are illusory tools for assessing evidence. They should be replaced by a diversity of approaches that involve analyzing the totality of theevidence-base”3
