Univariate Linear Regression Plots
(A) ΔEF vs ΔHAT, (B) ΔEF vs ΔSS, and (C) ΔSS vs ΔHAT. ΔEF significantly (p < 0.01) and positively correlated (R2 = 0.69) with ΔHAT, but significantly (p = 0.03) and negatively correlated (R2 = 0.40) with ΔSS. ΔSS was significantly (p = 0.03) correlated (R2 = 0.39) with ΔHAT. ΔEF = change in left ventricular ejection fraction; ΔHAT = change in helix angle transmurality; ΔSS = change in scar size.
