  1. * < 0.05. Data are in numbers and percentages [n (%)], TFV is tenofovir. VAS is visual analog scale. CAS is composite adherence score
  2. aLogistic regression; cOR is crude odd ratio; aOR is adjusted odd ratio
  3. bAdjusted for age, sex, ethnicity, marital status, work status, education experience, monthly household income, duration of HIV diagnosis, ART regimen and duration of TDF-based ART
