^aPer South Carolina Medicaid birth year cohort.

^bPrevention fraction (1-relative risk) of male circumcision for reducing HIV transmission through heterosexual contact.

^cUsing Schackman et al.'s discounted lifetime HIV treatment cost (discounted to time of infection) of $303,100 (in $US2004) inflated to $US2010 for a lifetime treatment cost of $377,360.

^dTo allow for direct comparison to circumcision savings in the cohort birth year.
