Randomized Controlled Trial | Study designs | Epidemiology in Minutes | EpiMinutes 6

Randomized control trials (RCTs) are the best form of study designs involving primary data collection, especially for finding any association between exposure and outcome. Although it cannot be applied for all exposures or interventions, and can be quite time and resource consuming. In this mini-presentation of EpiMinutes, I am giving a brief overview of the very basics of RCTs, with an example. I hope this will be helpful as an introduction to this very robust but challenging study design.
Also, I thought that I would keep the video on so that you could see me and put my name on a face! 😊

Thanks for video!, how can i calculate my population to investigate?

At around the 7:16/18 min, you say (encircling on the slide) that the investigator assigns who gets what treatment. If the investigator assigns who gets what, doesn’t that make it a quasi experimental design? Since the participants are not randomly assigned to the groups. Since you went ahead to mention randomization, I can only assume it’s a language sth and u meant to say something else.

[@epiminutesbykazi]

Thank you for your comment. It is the investigators who assign who gets what in an interventional study as opposed to an observational study where investigators have no role on exposure assignment. Now, the investigator may assign exposure/intervention either using randomization or not.
