Frequently Asked Questions
What is an observational study design?
A research approach in which investigators observe patients and outcomes in routine care without assigning a treatment, such as a cohort, case-control, or cross-sectional study.
What is the difference between a retrospective and a prospective cohort study?
A retrospective cohort study uses data already collected, such as healthcare records. A prospective cohort study enrolls patients and follows them forward in time.
What is the difference between a cohort study and a case-control study?
A cohort study starts with an exposure and follows patients to an outcome. A case-control study starts with the outcome and looks back at past exposures.
What is a retrospective cohort study?
It uses existing data, such as healthcare records or claims, to group patients by an exposure and compare their outcomes over a past period.
What is the difference between a cohort study and a cross-sectional study?
A cohort study follows patients over time. A cross-sectional study measures exposures and outcomes at a single point, so it describes burden but not timing.
