MMSE = Mini-Mental State Exam. FACIT-F = Functional Assessment of Chronic Illness Therapy Fatigue scale. CES-D = Center for Epidemiologic Studies Depression scale. ◆CVD disease defined as a history of heart attack, coronary/myocardial infarction, stroke/brain hemorrhage, heart failure/congestive heart failure or abnormal heart rhythm. Values are reported as means ± SD for continuous variables and or n (%) for categorical variables. Significance set at *P < 0.05.
