Study Notes
Measures of Association
- The strength of association in a cohort study is measured by the Relative Risk (RR).
Relative Risk (RR)
- An RR value of 1 indicates no association between the exposure and outcome in descriptive epidemiology.
Types of Studies
- A cohort study is also known as a Forward/Prospective/Cause-Effect/Exposure to Outcome study.
- A case-control study is also known as a Backward/Retrospective/Effect-Cause/Disease to Risk study.
Population Attributable Risk (PAR)
- The major problem associated with PAR is that it is sensitive to the prevalence of the exposure in the population.
