Each parameter is varied through the range shown in parentheses, followed by a semicolon and the base case input value. Incremental cost-effectiveness ratios (ICERs) for the comparison of adherence intervention to standard-of-care, in $/quality-adjusted life-year (QALY) are shown on the horizontal axis. The range of ICERs for each varied parameter is indicated by the blue horizontal bars. Longer blue horizontal bars indicate parameters to which the model results are more sensitive. The vertical black line represents the base case ICER.
Abbreviations: ART, antiretroviral therapy; LTFU, loss to follow-up; ICER, incremental cost-effectiveness ratio; RTC, return to care.
