Global Line Plots and Normalized Changes of SS, |HAT|, and EF for Both CDC_EXO and Placebo Groups

Global line plots (top) and normalized changes (bottom) demonstrate baseline values for SS, |HAT|, and EF were comparable between both groups. The CDC_EXO group exhibited significant (p < 0.05) reduction in SS but no significant changes in |HAT| and EF. The placebo group revealed significantly reduced |HAT| and EF but no change in SS. EF = ejection fraction; SS = scar size; other abbreviations as in Figures 1 and 3.
