Summary of the estimates of adjusted hazard ratios associated with our two migration indices.
| Men | Women | |||
| Risk factor | Adjusted hazard ratio (95% CI) | P value | Adjusted hazard ratio (95% CI) | P value |
| Time outside | 2.54 (1.67–3.85) | <0.0001 | 1.57 (1.14–2.17) | 0.00602 |
| Log (1 + migration distance) | 1.12 (1.06–1.17) | <0.0001 | 1.09 (1.05–1.13) | <0.0001 |
We fitted Cox proportional hazards models for men and women men that estimate repeat-testers’ hazard of HIV seroconversion conditional on each migration index, and on several known sexual and sociodemographic risk factors of HIV acquisition: reporting more than one partner in the previous 12 months over the duration of the study, marital status, number of years of education, perceived financial status, age, age2, and age3. The full output from these models is given in Tables S5 and S6 in the Supporting Information.
