2 Baseline Covariates for 3 Cohorts of New Statin Users
Sebastian Schneeweiss, et al. Circulation 2007;115:

3 Adherence for the baseline, copayment, and coinsurance cohorts
Adherence for the baseline, copayment, and coinsurance cohorts showing a sudden decline in adherence  100 days (equal to the median prescription supply) after the policy changes. Adherence was measured as the proportion of patients with >80% of days covered during each month. Unadjusted proportions were plotted. Sebastian Schneeweiss, et al. Circulation 2007;115:

4 New initiations of statin therapy after AMI at baseline and under a copayment and coinsurance policy
New initiation of statins was defined as not having used a statin for at least 6 months before the index MI. Q indicates quarter. Sebastian Schneeweiss, et al. Circulation 2007;115:
