Does anyone have a mnemonic or something like that to remember the difference between the two and which is retro and which is prospective?
Any help appreciated!

Case control: compares what two separate populations look like right now - I always think of it as a snapshot or a instant in time, and therefore you can't establish causation with case/control. Cheap, easy to conduct.Does anyone have a mnemonic or something like that to remember the difference between the two and which is retro and which is prospective?

Prospective cohort: you look at one group and watch them. People fall out on risk factors or prevalence of disease. Think about looking into the future and letting God sort them out. Goes towards establishing causality and is expensive, time-consuming to conduct, but the brass ring of studies.
Retrospectives: kinda like prospective cohorts, but you're looking at old data. The others need subjects, retrospectives need patient charts.

A cross-sectional will also get you a snapshot in time.I might be wrong, but I certainly thought case-control was a retrospective study. You look at people with the disease, and see what risk factors they had. Cross-sectional is the snapshot in time you speak of...
