MAPV Mean arterial pressure variability, POD Postoperative delirium, PSM Propensity score matching, OR Odds ratio, CI Confidence interval
^aThe ORs of MAP > 2.17
^bModel 2 included age, sex, BMI, ASA, hypertension, diabetes mellitus, cardiovascular disease, cerebrovascular disease, COPD, dementia and alcohol consumption
^cModel 3 included WBC count, RBC count, haemoglobin level, albumin level, anaesthesia method, duration of surgery, and use of benzodiazepines, dexmedetomidine or glucocorticoids
^dModel 4 included for model 2 plus model 3
^eModel PSM was a multivariate regression mode and included for model 2 plus model 3
