Case-Control Study: Design
|
* OBSERVATIONAL & RETROSPECTIVE *
- Compares a group of people with disease to a group without disease - Looks for prior exposure or risk factor - Asks "what happened?" |
- Measure: Odds ratio (OR)
- E.g., "patients w/ COPD had higher odds of a history of smoking than those without COPD had" |

Cohort Study: Design
|
* OBSERVATIONAL & PROSPECTIVE OR RETROSPECTIVE *
- Compares group with given exposure/risk to group without exposure - Did exposure increase likelihood of disease - Prospective ("who will develop disease?") vs Retrospective ("who developed disease?") |
- Measure: Relative risk (RR)
- E.g., "smokers had a higher risk of developing COPD than nonsmokers had" |
