From: HIV transmission dynamics and population-wide drug resistance in rural South Africa

Beneath threshold: less than half of the sites had sufficient data at the stipulated threshold to determine resistance. Susceptible: all relevant sites had read at the stipulated threshold, and no mutations were detected. Data for four drug classes are shown. NRTI nucleoside reverse transcriptase inhibitor, NNRTI non-nucleoside reverse transcriptase inhibitor, INSTI integrase strand transfer inhibitor, PI protease inhibitor.
