Projected Average Cost and Effectiveness of Directly Observed HAART in 5000 Simulated Randomized Trials.

NOTE: HAART, highly-active antiretroviral therapy; QALY, quality-adjusted life years.
* A health care intervention is “dominated” if it costs more, but provides less health benefit, than a competing intervention. A dominated health intervention is never preferred [50]. A health care intervention is considered to be “cost-saving” when it costs less, but provides more health than, a competing intervention; “highly cost-effective” when it costs less than the GDP per capita; and “cost-effective” when it is between one and three times a country's GDP per capita. A cost-saving intervention is always preferred [49], [50].
