Numbers in bold are significantly different from the Treatment-naive viruses at the p < .05 level.
Treated (2) and treated (3) refer to groups of NRTI-experienced and of NRTI+NNRTI-experienced patients, respectively, as described in the Methods section.
NRTI+NNRTI, nonnucleoside reverse transcriptase inhibitors.
