Cohort Studies
A type of epidemiological study, but not the broad category itself.
Cohort studies follow a specific group over time to see how exposure influences disease risk.

Cross-Sectional Studies
Cross-sectional research is a study design that collects data from a population at a single point in time. It examines relationships between variables, identifies patterns, and measures prevalence. Unlike longitudinal studies, it does not track changes over time but provides a quick, cost-effective snapshot of a population or phenomenon.

Case Studies
Focus on individual or small group analysis, not large-scale prediction.
