Sensitivity analysis and scenario analysis.

Timing of the breakeven point (year) and cumulative number of life-years saved (x 1000) of treating patients according to the new WHO guidelines compared to ≤200 cells/µl are shown. The breakeven point shows when cumulative net cost savings will occur.*Effects of 10% increase and decrease in partner change rates are displayed as dotted lines in figure 1D, 4A and 4B.**Applied to all 5 health seeking rates (rh(1) to rh(5), see Supplementary Material S1.***Applied to all cost values displayed in table1.****All scenarios changes is the scenario analysis take effect in 2015.N.A. = Not Affected.
