Table 2 Preoperative baseline demographics and clinical characteristics, median (interquartile rage)

	Surgeries without complications (n = 32389)	Surgeries with complications (n = 373)	P value
Median age	73 (67-79)	73 (66-80)	0.811
Sex (female, male)	18713, 13669	210, 163	0.563
BMI	26.2 (24-31)	28 (24-31)	0.761

P < 0.05 is considered statistically significant. P-value was calculated using the modified Poisson model. BMI: Body mass index.
