Baseline Characteristics

Because this was an observational study, the backgrounds of the two groups were not aligned, and a propensity score was used to align the backgrounds of the two groups.

Participant flow

All events were followed up until initial discharge.

Adverse events

This is an observational study and no adverse events have occurred that originated from this study.

Outcome measures

The primary endpoint was occurrence of delirium within 5 days postoperatively. Secondary endpoints were occurrence of delirium during ICU stay, occurrence of delirium during hospitalization, duration of delirium, occurrence of subsyndromal delirium during ICU stay, and change in MMSE (preoperative to 2 days postoperative, preoperative to 5 days postoperative).
