Method: Several additional DRMs not on the SDRM list were analyzed including (1) the primarily tenofovir disoproxil fumarate (TDF)-selected DRMs
A62V,
K65N, and
K70G/N/Q/S/T and (2) the primarily rilpivirine (RPV)-selected DRMs
E138A/G/K/Q, of which
E138A is polymorphic, occurring in 1%-4% of viruses from ART-naive individuals.
