A cohort study is an observational design that follows one or more groups, defined by their exposure status, forward in time to compare the rates at which outcomes develop. Prospective cohorts identify participants and plan measurements at the outset, allowing complete and consistent data collection, whereas retrospective cohorts reconstruct exposures and outcomes from existing records. Cohort designs can estimate incidence and relative risk and are a valuable source of real-world evidence on the long-term effectiveness and safety of devices, complementing the controlled conditions of trials. Their principal threat to validity is confounding, since exposure is not randomly assigned, so careful design and statistical adjustment are needed to support causal interpretation.
