Patients Two hundred ninety-seven antiretroviral-experienced, protease inhibitor-naive, clinically stable HIV-infected children aged 2 to 17 years. Interventions Children were randomized to receive zidovudine, 160 mg/m2 3 times per day, plus lamivudine, 4 mg/kg 2 times per day (n=100) ; the same regimen plus ritonavir, 350 mg/m2 2 times per day (n=100) ; or ritonavir, 350 mg/m2 2 times per day, and stavudine, 4 mg/kg 2 times per day (n=97).
