Data are mean proportion and mean difference (95% CI; 90% range reflecting variation across setting scenarios) compared with the policy of tenofovir, lamivudine, and efavirenz for all, unless otherwise indicated. DALYs and net DALYs were measured over 20 years (2018–38) and represent the mean over 3 month periods, unless otherwise stated. Costs are in US$. ART=antiretrovoral therapy. DALY=disability adjusted life-year.
As opposed to tenofovir disoproxil fumarate, all are on lamivudine.
Neural tube defects potentially caused by dolutegravir if possible signal is confirmed.
In the context of an adult population of 10 million people with HIV prevalence as in table 2. Costs and DALYs are discounted at 3% per annum.
Values are mean and mean difference (95% CI; 90% range reflecting variation across setting scenarios).
Values are n per year (95% CI; 90% range reflecting variation across setting scenarios).
Policies are dominated if there is another policy with both lower cost and more DALYs averted. The reference policy is selected among non-dominated policies.
