Clinical research relies on a range of study approaches to answer questions about health interventions and outcomes. Randomized trials are designed to determine causal effects by randomly assigning participants to different interventions, which helps prevent bias from confounding. Observational studies examine what happens in real-world settings without random assignment, providing important information about effectiveness, safety, and rare outcomes when trials aren’t feasible. Evidence synthesis, such as systematic reviews and meta-analyses, combines findings from multiple studies to draw more robust conclusions and guide clinical practice and policy. Because each type contributes unique strengths and insights, the full scope of clinical research includes randomized trials, observational studies, and evidence synthesis, making the combined option the most comprehensive answer.
