How DI Is Flagged
PPG-1 = subgroup rate − all other rate
For positive outcomes, disproportionate impact is flagged when PPG-1 ≤ −E.
E = max(1.96 × sqrt(p̂(1−p̂)/n), 2.0%)

- Groups with
n ≤ 10are marked as insufficient data. - Each analysis cell shows the all-other rate, margin of error, and gap-closing estimate.
- Counts must follow
