Intervention methods are evaluated through various research designs and methodologies to ensure their effectiveness and safety. Key approaches include:
- Randomized Controlled Trials (RCTs): These are considered the gold standard for evaluating the efficacy of interventions. Participants are randomly assigned to intervention or control groups to compare outcomes. - Cohort Studies: Observational studies that follow a group of individuals over time to assess the impact of interventions. - Case-Control Studies: These studies compare individuals with a disease (cases) to those without (controls) to identify factors associated with the disease and evaluate interventions.
