Comparison of transmitted drug resistance mutations (TDRMs) and predicted phenotypic resistance (Stanford scores) by drug class, 2010–2013
| ART drug class | Surveillance mutations | Predicted phenotypic resistance to currently recommended first‐line ART | ||
|---|---|---|---|---|
| % any TDRM | % any low level/intermediate/high level | % any intermediate/high level | % any high level | |
| Any class | 7.5 | 9.6 | 3.9 | 2.8 |
| NRTI | 3.5 | 1.2 | 0.8 | 0.6 |
| NNRTI | 3.3 | 8.2 | 3.5 | 2.6 |
| PI | 1.7 | 0.9 | 0.2 | 0.1 |
ART, antiretroviral therapy; NRTI, nucleoside reverse transcriptase inhibitor; NNRTI, nonnucleoside reverse transcriptase inhibitor; PI, protease inhibitor.
