Estimates, standard errors, p-values, adjusted ORs, and 95% CIs for variables associated with MACE in the full PN-A₄CH logistic regression model.

Factor	Estimate	SE	p-value	Adjusted OR	95% CI
Age (⩾ 75 years)	0.779	0.322	0.016	2.18	(1.16–4.09)
Anemia	0.668	0.294	0.023	1.95	(1.10–3.47)
ASA class (>2)	1.124	0.399	0.005	3.08	(1.41–6.73)
Approach (open surgery)	1.032	0.312	<0.001	2.81	(1.52–5.17)
Creatinine (⩾1.5 mg/dl)	1.230	0.324	<0.001	3.42	(1.81–6.45)
Heart disease	1.006	0.371	0.007	2.74	(1.32–5.66)

Adjusted OR, adjusted odds ratio; ASA class, American Society of Anesthesiologists classification; 95% CI, 95% confidence interval; MACE, major adverse cardiovascular events; SE, standard error.

Approach is surgical approach; creatinine is preoperative serum creatinine in mg/dl; heart disease is history of myocardial infarction, percutaneous intervention, cardiac surgery, or congestive heart failure.
