Cross-sectional study compares individuals from different birth cohorts at the same time. Retrospective study looks back in time to compare individuals who have a specific condition or exposure with those who do not. Introspective study is not a commonly used term. Longitudinal study follows a group of individuals over a period of time to observe changes and outcomes.
