Univariate and multivariate analysis of plasma AOPPs after operation for prediction of ALI

	Univariate		Multivariate
	OR (95 % CI)	P	OR (95 % CI)	P
AOPPs 1 h after operation	1.148 (1.065, 1.237)	<0.001	1.164 (1.068, 1.269)	0.001
Age	1.103 (1.041, 1.168)	0.001	1.054 (0.984, 1.129)	0.130
COPD	9.615 (1.671, 55.314)	0.011	28.706 (1.770, 465.64)	0.018
Diabetes mellitus	10.20 (0.987, 105.38)	0.051	1.485 (0.085, 26.040)	0.787
Hypertension	8.167 (1.781, 37.449)	0.007	0.665 (0.059, 7.501)	0.741
BMI	1.147 (0.984, 1.336)	0.079	0.998 (0.758, 1.313)	0.989
Systolic BP	1.049 (1.001, 1.099)	0.052	1.061 (0.982, 1.147)	0.133

P < 0.10 in the univariate analysis were candidates for the multivariable logistic analysis (including variables: AOPPs 1 h after operation, Age, COPD, diabetes mellitus, hypertension, BMI and systolic BP)
