Studies in which biomedical and/or health outcomes are assessed in pre-defined groups of individuals. Subjects in the study may receive diagnostic, therapeutic, or other interventions, but the investigator does not assign specific interventions to the subjects of the study.

NOTE: Major subtypes of observational studies are cohort study, case-control study, and cross-sectional study.
