Multivariate analysis of variables examined as potential predictors of AKI after TJA adjusted for confounding variables.

Variables	Odds ratio	P value	95% CI
BMI	1.051	.098	0.99-1.11
Preoperative SCr	7.23	.001	2.33-22.39
Postoperative Hb difference	2.59	<.0001	1.84-3.64
EBL	1.00	.110	1.00-1.00
Bilaterality	2.12	.282	0.54-8.36
Duration of surgery	1.01	.083	1.000-1.03
High ASA score	3.28	.03	1.13-9.51

Bold values indicate that there is a statistically significant association between the variable and post-operative AKI development (P < .05).
