Table 4 Univariate and multivariate analysis of plasma AOPPs after operation for prediction of ALI

From: Plasma level of advanced oxidation protein products as a novel biomarker of acute lung injury following cardiac surgery

  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

  1. 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)
  2. ALI acute lung injury, Systolic BP systolic blood pressure
