Preexisting Resistance to Nonnucleoside Reverse‐Transcriptase Inhibitors Predicts Virologic Failure of an Efavirenz‐Based Regimen in Treatment‐Naive HIV‐1–Infected Subjects

Abstract
A case-cohort study was used to determine the effect of baseline nonnucleoside reverse-transcriptase inhibitor (NNRTI) resistance, as assessed by vir
