Table 4 Overall adherence rates across methods

From: Adherence evaluation of endocrine treatment in breast cancer: methodological aspects

Assessment Method Number of patients (%)
  Adherent CL 95%
Plasma concentration a 98.2% 95-99%
Physician rating 92.1%* 88-95%
Prescription refill (6months)b 85.3%* 78-90%
Self-rating 82.6%*+ 77-87%
Overall prescription refill b 77.8%*+ 70-83%
  1. a plasma concentrations below the quantification limit indicate non-adherence (see Methods section).
  2. b an MPR of >90% was classified as adherent.
  3. * significant lower adherence rate than adherence rate indicated by plasma concentration.
  4. + significant lower adherence rate than adherence rate indicated by physician-rating.
