Table 2 Logistic regression model for in-hospital mortality in relation to plasma haptoglobin levels

From: Association between haptoglobin, hemopexin and mortality in adults with sepsis

Characteristic Odds ratio 95% confidence interval P-value
Age, years 1.022 1.004, 1.041 0.016
APACHE II score 1.075 1.040, 1.111 <0.001
Chronic liver disease 2.567 1.099, 5.999 0.029
Cell-free hemoglobin level (log, mg/dl) 2.152 1.324, 3.497 0.002
Haptoglobin (log, μg/mL) 0.653 0.433, 0.984 0.042
  1. Odds ratios are per one year increase in age, one point increase in Acute Physiology and Chronic Health Evaluation (APACHE II) score, the presence versus absence of chronic liver disease, one log increase in cell-free hemoglobin, and one log increase in haptoglobin level.
