OLA: oligonucleotide ligation assay; CS: consensus sequencing; IQR: interquartile range; NS: not significant at p = .05; ARV: antiretroviral; PI: protease inhibitor; NRTI: nucleoside reverse transcriptase inhibitor; NNRTI: non-nucleoside reverse transcriptase inhibitor therapy.*differences between groups were not significant in analyses that were both unadjusted and adjusted for time from infection to the date of sampling.
