Table 4 Cox regression analyses to predict 30-day and 6-month mortality

From: Sustained high serum malondialdehyde levels are associated with severity and mortality in septic patients

  Hazard ratio 95% confidence interval P-value
Model: mortality at 30 days    
MDA serum levels at first day 1.05 1.02 to 1.09 0.005
Lactic acid levels at first day 1.11 1.06 to 1.16 <0.001
APACHE-II 1.03 1.01 to 1.04 0.007
Diabetes mellitus 1.46 0.97 to 2.22 0.07
Bloodstream infection 0.85 0.49 to 1.48 0.56
Chronic renal failure 1.16 0.61 to 2.21 0.66
Model: mortality at 6 months    
MDA serum levels at first day 1.05 1.02 to 1.09 0.003
Lactic acid levels at first day 1.11 1.06 to 1.16 <0.001
APACHE-II 1.02 1.01 to 1.04 0.003
Diabetes mellitus 1.55 1.07 to 2.25 0.02
Bloodstream infection 0.73 0.44 to 1.23 0.23
Chronic renal failure 0.85 0.45 to 1.62 0.63
