    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 NNRTI 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
