R2.4: explain further HIV prevalence vs ART impact relationship

[jessexknight]

As HIV prevalence is linked to epidemic type, it's interesting that ART prevention impacts were larger with lower HIV prevalence. As the lower prevalence epidemics in West Africa are driven by KPs/more so than the epidemics in ESA, I assume that modelling studies in West Africa are more likely to be KP-disaggregated. However, you have shown that KP-disaggregated models estimate smaller ART prevention impacts. Could this be explored further?
