Note: Mental HRQOL is single regression model containing all drugs shown and adjusted for age, race, gender, education, and site. Physical HRQOL is single regression model containing all drugs shown and adjusted for age, race, gender, education, use of highly active antiretroviral therapy, CD4 nadir and site.
