Sensitivity and resistance of different mutation sites in HIV-1 CRF_BC pol region to NNRTIs using an in vitro phenotypic assaya.

Note:aThe unit for the EC50 values of TMC-125 and EFV is nM, while that for the EC50 values of DLV and NVP is µM. Data were presented as the mean ± standard deviations of three separate determinations.bWT: HIV-1 CRF_BC strain N-14-1.cFold change was determined by calculating the ratio of EC50s for mutations and WT viruses.
