Fig. 1. Kaplan-Meier survival curve showing major adverse cardiac event (MACE)–free survival in the group of patients with deterioration in wall motion score (WMS) compared with the group that showed either no change or improvement in WMS up to 24 months after surgery.  P value indicates between-group difference. “Deterioration” is represented as a binary variable (post–cardiopulmonary bypass WMS > pre–cardiopulmonary bypass WMS).  Hashed lines on either side of the  solid line for each group indicate the 95% confidence interval for MACE-free survival. CABG = coronary artery bypass graft.
