Summary of 50% inhibitory concentrations (IC₅₀) determined by infecting TZM-bl cells with HIV-1 BaL.

a<p>Data show the confidence interval (C.I.) based on the 2.5 and 97.5 percentiles of bootstrapped IC₅₀ estimates, and the coefficient of variation (Cv) of the IC₅₀ of each drug alone and in combination.</p>b<p>Combined activities were evaluated using a 1∶1 ratio of IC₅₀ values, corresponded to the molar ratios of 1∶11 Free EFV∶Free TFV, 1∶5 Free TFV∶Free SQV, and 1∶3 Free TFV∶NP-SQV.</p>c<p>Combined activities were evaluated using a 1∶50 ratio of IC₅₀ values, corresponded to the molar ratios of 1∶11 Free EFV∶Free TFV.
