Patients harboring resistance-associated mutations (RAMs) in the reverse transcriptase gene identified by next-generation sequencing. The bars represent the percentage of the patients harboring mutations indicated on the horizontal axis: black bars for RAMs accounting for >20% of the virus population, dark gray bars for RAMs at 5%–20%, and light gray bars for RAMs accounting for 1% to <5%. *Mutations in the International AIDS Society list. Abbreviations: NNRTI, nonnucleoside reverse transcriptase inhibitor; NRTI, nucleos(t)ide reverse transcriptase inhibitor.
