HR=hazard ratio.

*Derived from male sexual behaviour in the surrounding local community with a standard Gaussian kernel (radius 3 km) around each woman in the cohort (figure 2).
Includes both male community-level mean lifetime partners and prevalence of concurrent partnerships covariates.
Unadjusted hazard ratio, 1·26 (p<0·0001).
