The design of a clinical study depends on its objectives. Common designs include:
Randomized Controlled Trials (RCTs): Participants are randomly assigned to either the treatment group or the control group to compare outcomes. Cohort Studies: Groups of individuals are followed over time to observe how different exposures affect outcomes. Case-Control Studies: Patients with a specific condition are compared to those without to identify potential causes or risk factors. Cross-Sectional Studies: Data is collected at a single point in time to assess the prevalence of conditions or risk factors.
