What is the main purpose of a randomized controlled trial (RCT)?

To combine results from multiple studies
To describe unique conditions
To follow groups over time to see if they develop an outcome
To randomize and sometimes blind patients to study outcomes

The correct answer is: To randomize and sometimes blind patients to study outcomes

The main purpose of a randomized controlled trial (RCT) is to randomize patients to different groups to study outcomes. This randomization helps to prevent any bias or confounding variables that may influence the results. Option A is incorrect because while meta-analysis may combine results from multiple studies, that is not the main purpose of an RCT. Option B is incorrect because an RCT is typically used to study a specific intervention or treatment in a controlled setting, rather than describing unique conditions. Option C is incorrect because cohort studies are typically used to follow groups over time to see if they develop an outcome, while an RCT typically compares outcomes between randomized groups.
