Table 2 Distributions according to death and an exposure variable: Dichotomous exposure
| Â | Nonexposed E0 | Exposed E | Total |
|---|---|---|---|
Death D | (1 - f) p0 | f R p0 | p |
No death | (1 - f) (1 - p0) | f (1 - R p0) | 1 - p |
Total | 1 - f | f | 1 |
- Let
- p = probability of death in population
- f = fraction of population exposed
- p0 = probability of death in the nonexposed
- R = relative risk
- It follows that for a dichotomous exposure variable, based on the second row of the table,
-
