Text: For the proportions of patients (intention-to-treat ; missing = failure) with HIV-1 RNA < 400 copies/mL (PI group, 66 % ; ABC/3TC/ZDV group, 71 %) and < 50 copies/mL (PI group, 63 % ; ABC/3TC/ZDV group, 62 %) at 96 weeks, switching to ABC/3TC/ZDV was noninferior compared with continuing the PI regimen ; the difference in failure rate (ABC/3TC/ZDV minus PI) was -4. 4 percentage points [95 % confidence interval (CI) -21. 0 to +12. 3 percentage points] and +0. 4 percentage points (95 % CI -16. 9 to +17. 7 percentage points), respectively.
