Cox proportional hazard regression models were used to calculate hazard ratios (HRs) with 95% confidence intervals
Crude model was adjusted for none
Model 1 was adjusted for age and gender
Model 2 was adjusted for model 1+ (MI, CHF, cerebrovascular disease, chronic pulmonary disease, rheumatic disease, diabetes, renal disease, liver disease, MV, and RRT).
Model 3 was adjusted for model 1 + model 2+ (serum hematocrit, MBP, temperature, SPO₂, potassium, INR, PT, and SOFA).
MI, myocardial infarction; CHF, congestive heart failure; MV, mechanical ventilation; RRT, renal replacement therapy; MBP, mean blood pressure; SPO₂, percutaneous oxygen saturation; INR, international normalized ratio; PT, prothrombin time; SOFA, Sequential Organ Failure Assessment
