All P-values are adjusted for the baseline value of the outcome measure. Entries are baseline-adjusted partial correlation coefficient between continuous predictors and outcomes and baseline-adjusted least square means ± SE of categorical predictors.

CVA = cerebrovascular accident; COPD = chronic obstructive pulmonary disease; CHF = congestive heart failure; LV = left ventricular; MI = myocardial infarction; PVD = peripheral vascular disease; ICU = intensive care unit; IADL = Lawton instrumental activities of daily living scale.
