Table 2 Possible presentation of a study with a preexisting exposure based comparison (cohort study not requiring a reanalysis)
Group 1 | Group 2 | Effect |
|---|---|---|
Absolute risk for outcome (e.g. mortality rate) in all exposed (e.g. treated) patients | Absolute risk for outcome (e.g. mortality rate) in all unexposed (e.g. not treated) patients | Risk ratio with 95% confidence interval (e.g. relative risk of mortality for treated vs. untreated) |
