  1. CI = 95% confidence interval of the mean. CHFBT = congestive heart failure patients before treatment. CHFAT = congestive heart failure patients after treatment. All comparisons between CHFBT and CHFAT performed with the Wilcoxon paired test. All comparisons between CHFAT and controls performed with Mann-Whitney test. Note: only CHF patients who completed the two phases of the study were included in the analyses. Information on the Trail Making Test was missing for one patient with CHF.
