  1. *All costs, life-years, and QALYs are discounted by 3% annual rate.
  2. ϮQALY = Quality-Adjusted Life-Year; ICER = Incremental Cost-Effectiveness Ratio.
  3. All QALYs are calculated using an adjustment of 0.82 utility per year when living with HIV and an annual discount rate of 0.03.
  4. The ICER value is calculated as follows: \( ICER=\frac{Cos{t}_{OptionB+}-Cos{t}_{OptionB}}{QALY{s}_{OptionB+}- QALY{s}_{OptionB}}. \)
