| SBP (intraoperative) | 114 (110–120) | 112 (107–118) | 0.056 |
| MAP variability (intraoperative) | 90 (61–122) | 81 (50–107) | 0.030 |
| MAP (PACU) | 98 (89–107) | 92 (83–103) | 0.006 |

| Mean arterial blood pressure before anesthesia induction and difference from baseline | |||
| n = 90 | n = 72 | ||
| Baseline MAP | 106 (100–115) | 106 (100–115) | 0.772 |
| ΔMAP (baseline—induction) | 20 (11–31) | 24 (19–29) | 0.06 |
| ΔMAP (baseline—intraoperative) | 24 (16–33) | 31 (26–39) | < 0.001 |
| ΔMAP (baseline—PACU) | 11 (− 3to 23) | 16 (7–24) | 0.047 |
Baseline MAP was calculated as the average of three non-invasive blood pressure measurements prior to induction of anesthesia. ΔMAP was defined as the difference between mean induction, intraoperative, or PACU MAP from baseline. Data are presented as median (interquartile range)
