Models evaluate association of PHQ symptoms of depression as predictor (independent) variable with cardiac function as outcome (dependent) variable. Age-adjusted mean adjusted for age only. Multivariable-adjusted mean adjusted for age, sex, marital status, diabetes, revascularization, smoking, body mass index, physical activity, antidepressant use, statin use, and creatinine clearance.
PHQ = Patient Health Questionnaire; CI = confidence interval.
