Multivariate logistic regression analysis of preoperative risk factors associated with major complications.

Variable	Odds Ratios (CI 95%)	p Value
CHD	1.91 (1.05–3.54)	0.0367
COPD	2.13 (1.11–4.26)	0.0264
Alcohol	2.16 (1.09–4.56)	0.0341
CTx	0.40 (0.26–0.61)	<0.0001
Type of Cancer	1.39 (0.86–2.25)	0.1786

CHD, coronary heart disease; COPD, chronic obstructive pulmonary disease; CTx, chemotherapy. Bold p-values, statistical significance (≤0.05). Marked red: associated with a decreased risk of major complications.
