  1. Linear regression models whether the dependent variable is the logarithm of price. The reference categories are: HIV Prevalence <2%; Low income countries; Volume 1st tercile
  2. * significant at 5%; ** significant at 1%; Robust 95% confidence intervals in parentheses ***API = AIDS Program Effort Index; +Abbreviation of the ARV drugs: EFV = efavirenz; ZDV = zidovudine; 3TC = lamivudine; NVP = nevirapine; d4T = stadivudine; ++CHAI = Clinton Foundation HIV/AIDS initiative; +++PEPFAR = President's Emergency Plan for AIDS Relief.
