Figure 1. Event-Free Survival: Cox Proportional Hazard Model.

Figure 1

Cox proportional hazards model results show the difference in composite event-risk for patients who were symptom-free, those who practiced above average self-care management, and those who practiced below average self-care management. Results shown controlling for age, gender, body mass index, Beck Depression Inventory II score, comorbid conditions, left ventricular ejection fraction, heart failure etiology, New York Heart Association functional class, prescription of ACE inhibitors or ARBs, and/or β-adrenergic blockers, Duke Activity Status Index total score, Minnesota Living with Heart Failure Questionnaire total score, Medical Outcomes Study specific adherence score, and Self-Care of Heart Failure Index maintenance and confidence subscale scores.

Abbreviations: ACE = angiotensin converting enzyme, ARB = angiotensin receptor antagonist, ER = emergency room, HR = adjusted hazard ratio.
