Do you know what a Randomised Controlled Trial (RCT) is? How and why are such trials conducted? Today, the 28th of Feb is World Science Day and hence in true FutureIQ style, it seemed fitting to talk about one of the pillars of good science - RCTs.In this episode, we speak about the need for RCTs and how they came about to be. What are the different groups/phases within Randomized Controlled Trials? How does the Placebo effect play a role within RCTs? Along with giving several examples, we also explain the different variables and baises that are addressed through RCTs such as Observer Bias, Confounders Bias and Selection Bias.While RCTs are a pretty common and standardised practice within epidemiology, there are natural questions that arise about the ethics of the practice as well. How fair is it to the participants of the trial? And where does the line of morality lie in finding the balance for the greater good of the world?
