Accuracy of Tropism Assays Relative to the Enhanced-Sensitivity Trofile™ Assay.^{^a}

aValues are mean percentages (95% confidence interval of the mean), calculated assuming a binomial distribution of the data. bG2P FPR, Geno2Pheno[coreceptor] false positive rate used for population and 454 sequencing to assign CXCR4 use . The Geno2Pheno[coreceptor] clonal model was always used. cMT-2, Direct cocultivation of patient-derived peripheral blood mononuclear cells with MT-2 cells. dPPV, Positive Predictive Value. eNPV, Negative Predictive Value. f“Accuracy” is defined as: (True positives + True negatives)/Total.
