| NNRTI | Susceptibleb [n (%)] | Partially resistantb [n (%)] | Resistantb [n (%)] | Number of isolates |
|---|---|---|---|---|
| Nevirapine | 858 (51) | 62 (4) | 761 (45) | 1681 |
| Efavirenz | 973 (58) | 147 (9) | 554 (33) | 1674 |

| Rilpivirine | 109 (64) | 26 (15) | 35 (21) | 170 |
aNumber of isolates determined following the exclusion of similar isolates from the same patient and isolates containing electrophoretic mixtures with major NNRTI-resistance mutations.
bSusceptible, <3-fold decreased susceptibility. Partially resistant, 3- to 10-fold decreased susceptibility. Resistant, ≥10-fold decreased susceptibility.
