  1. p-value and lsmean for compliance level based on analysis of covariance (ANCOVA) model controlling for patient age, gender and race/ethnicity; Since only one individual in the study was classified as a high complier, analyses were conducted among low and medium compliers only.
  2. Effect size based on Cohen's d;
