MBG, mean blood glucose; POD, postoperative delirium; OR, odds ratio; CI, confidence interval; Ref, reference.

Model 1: unadjusted model.

Model 2: adjusted for age, HR, and SpO₂.

Model 3: adjusted for age, HR, SpO₂, RDW, hematocrit, eGFR, INR, PT, BUN, bicarbonate, and Na.

Model 4: adjusted for age, HR, SpO₂, RDW, hematocrit, eGFR, INR, PT, BUN, bicarbonate, Na, SOFA, and CCI.

Model 5: adjusted for age, HR, SpO₂, RDW, hematocrit, eGFR, INR, PT, BUN, bicarbonate, Na, SOFA, CCI, sepsis, CKD, mechanical ventilation use, and vasopressor use.

The bold values provided means statistically significant (namely P<0.05).
