摘要

Scientifically valid studies provide the best estimates of the truth, which is why we trust their results. Valid studies of therapies rigourously comparing different interventions ensure that biases and confounders (factors which can inflate or deflate the effects of an intervention) are equally distributed between the groups under comparison. In the ideal study, patients under comparison are identical in every respect except for the intervention of interest. The method to achieve this level of scientific validity was introduced only 60 years ago, when the first randomized controlled trial (RCT) was performed. Adoption by regulatory agencies of this methodology as the gold standard has forever changed the face of clinical research.
