Improvement of the association between self-reported pill count and varenicline levels following exclusion of participants with misreported pill count: A commentary on Peng et al. (2017)

摘要

Introduction: We previously reported poor associations between salivary varenicline and pill counts, and a substantial overestimation of adherence by pill counts in "Measures and predictors of varenicline adherence in the treatment of nicotine dependence" (Peng et al., 2017). We have since conducted supplementary analyses characterizing, and then excluding, individuals with established inaccurate pill count recall.
