Feedback:
Clinical trials, which are studies designed to assess the effectiveness of clinical interventions, often involve a series of phases. Phase I is designed to finalize features of the intervention. Phase II involves seeking preliminary evidence of efficacy and opportunities for refinements. Phase III is a full experimental test of treatment efficacy. In Phase IV, the researcher focuses primarily on generalized effectiveness and evidence about costs and benefits.
