Multivariable linear regression analysis of postoperative haemoglobin after off-pump coronary artery bypass (OPCAB) versus on-pump coronary artery bypass (ONCAB) surgery (ONCAB surgery is reference group)

	Women (n = 3,684)		Men (n = 13,368)
	Multivariable^a B (95% CI)	p-value	Multivariable^b B (95% CI)	p-value
Postoperative haemoglobin level, mmol/l	0.256 (0.182–0.331)	<0.001	0.500 (0.457–0.544)	<0.001

^a Multivariable model corrected for age, obesity, diabetes mellitus, left ventricular ejection fraction (LVEF) <35% and triple-vessel disease

^b Multivariable model corrected for age, hypertension, LVEF <35, estimated glomerular filtration rate and triple-vessel disease
