What type of research uses a comparison group to evaluate the effects of an intervention?

Prospective Study

Clinical Trial

Meta-analysis

Randomized Control Trial

A Prospective studies are not necessarily designed to evaluate interventions with a comparison group. They are longitudinal studies that follow a group of individuals over time to observe and analyze outcomes.

B: Clinical trials also involve studying the effects of an intervention, but they may not always include a comparison group. They may have a control group, which does not receive the intervention, but not a comparison group, which receives another intervention.

C: Meta-analyses involve analyzing data from multiple studies to draw conclusions about a particular topic, but they do not necessarily involve a comparison group.

D: Randomized control trials (RCTs) are specifically designed to evaluate the effects of an intervention by randomly assigning individuals to receive the intervention or a placebo or another intervention. This allows for a comparison between groups and helps to determine the actual effects of the intervention.
