Effect of CCM on LV ejection fraction and all cause mortality. a An improvement in LVEF was observed at 6 months compared to baseline and was sustained for 24 months follow-up. Improvements in LVEF were similar between LVEF subgroups. b Kaplan–Meier Survival curves for all-cause mortality over the 2 year follow-up. Data are presented as survival function together with 95% confidence limits. *p < 0.05 vs. corresponding baseline. Changes from baseline to specific time points are tested with allowance for multiple comparisons using Sidaks method mixed effects models
