Discussion about randomized controlled trials (RCT) has been extensive in social media during this spring due to corona virus epidemic. This discussion was especially heated when “not so good” clinical trial was published stating that hydroxychloroquine is efficient in the treatment of corona virus disease (CoViD-19).
I drew this picture and posted it on Twitter. It´s my 2 cents for the discussion about randomization in general.
PS. I don´t usually watch videos posted online but I dared to watch this one by Darren Dahly. That 6 minutes was well spent!
