Table 4

Effects of preoperative anaemia on postoperative outcomes.

Outcome	Preoperative anaemia
	ORunadj (95% CI); value	ORadj−1 (95% CI); value
Prolonged LOS	1.72 (1.23–2.41);	2.12 (1.49–3.10);
Composite complication	1.31 (0.88–1.93);	0.97 (0.63–1.49);
Inhospital mortality	1.94 (0.58–6.51);	1.74 (0.49–6.18);

Results are shown as odds ratio (95% CI); patients without preoperative anaemia were used as the reference; OR_unadj = unadjusted odds ratio; OR_adj−1 = odds ratio; LOS = length of hospital stay.
