Impact of perioperative transfusion in patients undergoing resection of colorectal cancer liver metastases: A population-based study

Table 4 Associations between perioperative transfusion and length of hospital stay, in-hospital mortality, and postoperative complications

	Univariate	Multivariate
Linear regression	Β ± SE	Β ± SE
Length of stay	2.01 ± 0.37	1.51 ± 0.361
Logistic regression	OR (95%CI)	aOR (95%CI)
In-hospital mortality	4.42 (2.05, 9.51)	3.38 (1.57, 7.25)2
Overall postoperative complications	1.69 (1.33, 2.15)	1.67 (1.31, 2.13)3

¹Multivariate analysis was adjusted for sex, type of admission, chronic anemia, congestive heart failure, hypertension, and bed size of hospital;

²Multivariate analysis was adjusted for age, type of admission, extent of liver resection, and hypertension;

³Multivariate analysis was adjusted for congestive heart failure and hypertension. β: Estimate; SE: Standard error; OR: Odds ratio; aOR: Adjusted OR; CI: Confidence interval. Numbers in bold indicate statistical significance (P < 0.05).
