FIG 6.

Genotypic and phenotypic analysis of samples from EFV/NVP-experienced patients. Patient samples with NNRTI resistance-associated NNRTI resistance-associated amino acid substitutions were screened for NNRTI susceptibility in an in vitro phenotypic assay. The Stanford HIV Drug Resistance Database genotypic resistance scores are included for reference purposes. Light gray shading, FCs of >3.6 (ETR), >2.6 (RPV), >3.8 (EFV), and >2.8 (NVP); dark gray shading, FC of >10. Pt. patient number; STD, standard deviation.
