FIGURE 1 Patient selection flowchart
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.
