Figure 2. Cumulative survival rates according to the presence of postoperative delirium.

Figure 2.

The postoperative morality rates within 24–36 months of the followed participants after orthopedic surgery were calculated by using the Kaplan-Meyer analysis. Specifically, the 36-month mortality rate of participants with postoperative delirium (8/28, 29%) was significantly higher than that of participants without postoperative delirium (7/75, 9%) at the follow-up (P = 0.009, log-rank test). Symbols (+) indicate the censored data.
