    Footnotes:
  1. Shown minimum DRM prevalence ≥0.5%
  2. DRMs are ordered according to their incremental contribution to the %cumulative column.
  3. A complete list of all NRTI DRMs including those with lower scores can be queried using the form at the following page: Prevalence of DRMs by ARV-class, ARV and HIVDB mutation score. This page will contain data for K65N and K70E/G/Q/N uncommon NRTI DRMs that may be associated with minimally reduced TDF susceptibility.
