REGRESSION
To further examine our findings regarding network gender composition, we conducted a sensitivity analysis to test whether male and female network members varied in response to the intervention by the number of females present in the injection network. We repeated our Model 1 analysis, in which we incorporated a product term between study arm and network gender composition in our Cox regression, but we also stratified by gender. We calculated simple effects regardless of the significance of the product terms to examine trends.For men (n = 894) and women (n = 301), product terms were non-significant in both unadjusted (Reductions in HIV seroconversion risk by number of women in one’s injection network for intervention vs control participants, stratified by gender.
