FIGURE 2 ROC curves showing the duration that patients could postoperatively walk (A) 200 m or (B) 100 m as a prognostic indicator for late mortality (200 m walk: AUC = 0.878; P < 0.002, the highest accuracy at 30 days, sensitivity = 83.3%, specificity = 91.8%; 100 m walk: AUC = 0.878; P < 0.002, the highest accuracy at 20 days, sensitivity = 83.3%, specificity = 82%)
FIGURE 3 Kaplan–Meier survival curves of patients undergoing surgery for acute type A aortic dissection, excluding hospital deaths within 30 days. The control and elderly groups are represented by blue and red line, respectively. P values are determined by analyzing log-rank test
FIGURE 4 Kaplan–Meier survival curves of patients with or without walking difficulty after surgery for acute type A aortic dissection, excluding hospital deaths within 30 days. A, Patients with and without postoperative walking difficulty are represented by red and blue lines, respectively. B, Among the patients regaining ambulatory autonomy at discharge, the patients with and without postoperative walking difficulty are represented by red and blue lines, respectively.P values are determined by analyzing log-rank test.
