Great presentation. Thank You! In retrospective cohort studies, we don't select the population based on the exposure, we select random people and see who had the exposure and who had not, and then see who has developed the disease and who has not. Also, if we expose a population to treatment, it is not a prospective (observational study), it is an experimental study.

I have been searching about the difference since yesterday. Many sources illustrate the difference wrong, because they haven’t mentioned there is a retrospective cohort study. This is the best explanation I found !!
