Evidence-Based Practice / Unit 6   EBP 0805 short lesson, about 20 seconds

Case-Control Studies

Captions available

The idea

A case-control study starts from the outcome: it compares people who have a condition with people who do not, looking backward for what differed.

In practice

Patients with a condition and matched patients without, compared on prior exposures.

Where people slip

Working backward is efficient for rare outcomes and exposes the design to recall bias by construction.
