Table 4 Univariate and multivariate models

From: Preoperative serum h-FABP concentration is associated with postoperative incidence of acute kidney injury in patients undergoing cardiac surgery

Variable Univariate Model I Model II Model III Model IV Final model (p < 0.1) OR (95% CI)
Ln(h-FABP) 2.29 (1.08–4.88) 2.29 (1.08–4.89) 1.82 (0.78–4.24) 2.24 (1.01–4.94) 1.79 (0.73–4.39) 2.29 (1.08–4.88)
eGFR 0.99 (0.97–1.02) 0.99 (0.97–1.02) - - 0.99 (0.96–1.02) -
Age 1.06 (1.00–1.11) - 1.04 (0.98–1.10) - 1.03 (0.97–1.09) -
Ln(TropT) 1.33 (0.74–2.39) - - 1.11 (0.60–2.05) 1.15 (0.62–2.13)  
  1. Determinants of AKI; data is presented as OR (CI95%); ln(h-FABP) to achieve normal distribution ln of FABP was calculated; final model is based on backward elimination.
