Estimated percentage of patients remaining alive and on antiretroviral therapy at 6-months as a result of proportional reductions in the historical quarterly death and loss to follow-up rates, stratified by BMI. The effect of a proportional reduction in quarterly loss to follow-up rates is represented by the diagonal lines, and the effect of a reduction in quarterly mortality rates is shown on the x-axis. Locate a mortality reduction value (0 to 50%) on the given loss to follow-up reduction line, and the percentage of patients estimated to remain alive and on ART at 6 months as a result of the assumed changes is shown on the y-axis. The historical program retention rate corresponds to the y-intercept of the lowest diagonal line (i.e., no assumed reduction in loss to follow-up). Abbreviations: ART, antiretroviral therapy; BMI, body mass index.
