CHF, congestive heart failure; COPD, chronic obstructive pulmonary disease; CRI, chronic renal insufficiency; CVA, cerebrovascular accident; DM, diabetes mellitus; HTN, hypertension; IHD, ischemic heart disease; LOD, late-onset depression; SD, standard deviation. The paired t-test was used for comparing the means of age, while McNemar’s test can be used to compare proportions of gender, COPD, DM, HTN, IHD, CHF, CVA, and CRI.
