Model-Estimated Probabilities of Detectability for Various Combinations of Predictors

Predictor Combination	12 Weeks Postswitch Estimated Probability of HIV RNA ≥50 Copies/mL (95% CI)	24 Weeks Postswitch Estimated Probability of HIV RNA ≥50 Copies/mL (95% CI)
Preswitch HIV RNA <50 copies/mL No documented nonadherence	0.03 (0.01–0.10)	0.03 (0.01–0.10)
Preswitch HIV RNA ≥50 copies/mL No documented nonadherence	0.38 (0.18–0.63)	0.35 (0.17–0.59)
Preswitch HIV RNA <50 copies/mL Documented nonadherence	0.21 (0.07–0.50)	0.23 (0.09–0.47)
Preswitch HIV RNA ≥50 copies/mL Documented nonadherence	0.84 (0.54–0.96)	0.82 (0.52–0.95)

Abbreviation: CI, confidence interval.
