*for those not meeting presumptive treatment criteria.
**assuming 100% compliance with waiting for positive results and accepting same-day treatment.
***assuming 0% failure to return rate, and 100% compliance waiting for positive results and accepting same-day treatment.
****assuming 20% failure to return rate if not treated same-day in clinic.
