| 60 percentage points | 0·70 (0·55–0·89) |
| 70 percentage points | 0·66 (0·50–0·87) |
| 80 percentage points | 0·62 (0·45–0·85) |

Data are adjusted for opposite-sex household HIV prevalence and the other independent variables included in the opposite-sex model; the effect size for each percentage-point increase will be the same irrespective of the baseline coverage.
