Probability of adherence
 Patel et al. [11] Adults taking a CCB or statin (but not both) who then initiated treatment with SPAA or added CCB to statin (or vice versa) Co-administration vs. single-pill administration PDC ≥80% % of patients with PDC ≥ 80 % ATR/AML: 67.7%
ATR+AML: 49.9%

[15] Patients with co-morbid hypertension and dyslipidemia at high risk for cardiovascular disease Co-administration vs. single-pill administration PDC ≥80% % of adherent patient Diabetes adherence OR (vs. noncoronary artery disease) Adjusted OR (95% CI): 1.06 (0.96. 1.17) Unadjusted OR (95% CI): 0.99 (0.90 1.08)
LDL-C level according to adherence level
