Feedback:
Systematic reviews are at the pinnacle of the hierarchy (Level I), because the strongest evidence comes from careful syntheses of multiple studies. The next highest level (Level II) includes individual randomized controlled trials (RCTs). Going down the rungs of the evidence hierarchy for Therapy questions results in less reliable evidencefor example, Level III evidence comes from a type of study called quasi-experiment. In-depth qualitative studies are near the bottom, in terms of evidence regarding intervention effectiveness.
