How is the Effectiveness of Interventions Measured?

In epidemiology, the effectiveness of weight management interventions is measured through various methods:

Randomized Controlled Trials (RCTs): These studies provide high-quality evidence by randomly assigning participants to intervention or control groups and comparing outcomes.
Cohort Studies: These observational studies follow groups of people over time to assess the impact of different interventions on weight and health outcomes.
Systematic Reviews and Meta-Analyses: These synthesize data from multiple studies to provide comprehensive evidence on the effectiveness of interventions.
