Question

Quizplus · Accepted Answer

A randomized clinical trial is essentially the same as a true experiment as participants are randomly assigned to either a treatment group or a control group. This allows for comparisons to be made between the two groups and for causality to be inferred. Retrospective and prospective studies are observational and do not involve randomization of participants. A meta-analysis is a statistical analysis of multiple studies, but it is not a specific epidemiological method.
