Cumulative HIV infections prevented over 20 years for male and female populations following implementation of 5-year expanded circumcision programs targeting: an additional 10% of uncircumcised adult males each year with no subsequent risk behavior change (panel A), with a 25% increase in condom use, corresponding to an absolute increase in condom use from 50 to 62.5% in circumcised males (panel B), or with a 25% decrease in condom use, corresponding to an absolute decrease in condom use from 50 to 37.5% in circumcised males (panel C); and similarly, an additional 20% of uncircumcised adult males each year with no subsequent risk behavior change (panel D), a 25% increase in condom use, corresponding to an absolute increase in condom use from 50 to 62.5% in circumcised males (panel E), or a 25% decrease in condom use, corresponding to an absolute decrease in condom use from 50 to 37.5% in circumcised males (panel F)
