Triglyceride-glucose index predicts postoperative delirium in elderly patients with type 2 diabetes mellitus: a retrospective cohort study

Table 2 Association between TyG index and POD with logistic regression models

Model	OR^a	95%CI	P value
Unadjusted model	1.668	1.210–2.324	0.002
Model 1 (adjusted for preoperative variables)	1.590	1.133–2.252	0.008
Model 2 (adjusted for intraoperative variables)	1.661	1.199–2.325	0.003
Model 3 (adjusted for all the variables)	1.603	1.137–2.283	0.008

OR^a is the odd ratio of TyG > 8.678; Preoperative variables include CKD, depression and anxiety, age, Hb, WBC, HDL, platelet count; Intraoperative variables include emergency surgery, surgery types, anesthesia time, blood loss, urine, Duration of MAP < 60 mmHg, Crystalloid, Colloid
