  • Randomized controlled trials (RCT) are prospective studies that measure the effectiveness of a new intervention or treatment. It provides a rigorous tool to examine cause-effect relationships between an intervention and outcome.
  • Examples of RCTs are clinical trials that compare the effects of drugs, surgical techniques, medical devices, diagnostic procedures or other medical treatments.
  • RCTs involve dividing a population into smaller groups, in order to comparatively see the outcomes of an external stimulus. For example, if the aim of a study is to understand whether a free grains distribution scheme helped improve the nutrition levels among people living in a district, researchers will first create two groups within the population, and then put people into those groups randomly.
  • RCTs also cannot be used to study something after it has happened, they need to be planned beforehand. And, while RCTs show results for a particular population in an area, it may not be proof that the same results will be achieved elsewhere, especially if the sample size is not big or the trial deals with a very specific kind of population sub-group.
