| Study ID | Location | Choice of model | Populations | Interventions | Time horizon | Projected health outcomes |

HIV, herpes simplex virus-2 and syphilis |
| Prinja et al21 | India | Dynamic Markov model | FSW, clients of FSW and general population (partners of clients) | Targeted FSW interventions—condoms and STI check-ups | 20 years (1995–2015) | Condom use, STI treatment and prevalence, HIV prevalence, cost per infection averted and DALY averted |
