A definition or brief description of Cross-sectional study.

Studies in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time. This contrasts with longitudinal studies which are followed over a period of time.

This definition is at least in part based on: Anonymous (2023), Cross-sectional study (English). Medical Subject Headings. U.S. National Library of Medicine.
