SF‐36 Summary Score	Model 1b OR (95% CI)	Model 2c OR (95% CI)	Model 3d OR (95% CI)	Model 4e OR (95% CI)
PCS	1.92 (1.29–2.86)	1.94 (1.30–2.90)	1.97 (1.32–2.95)	1.81 (1.20–2.74)

Abbreviations: CI, confidence interval; MCS, Mental Component Summary; OR, odds ratio; PCS, Physical Component Summary. ^aShort‐Form (SF‐36) Health Survey summary scores in units of 1 standard deviation. ^bModel 1: unadjusted association of SF‐36 and nonadherence. ^cModel 2: association of SF‐36 and nonadherence adjusted for age and sex. ^dModel 3: association of SF‐36 and nonadherence adjusted for age, sex, and problems with medications (perception of side effects, taking too many pills, or ineffectiveness). ^eModel 4: association of SF‐36 and nonadherence adjusted for age, sex, problems with medications, and ability to pay for medications.
