- Model 1 was the univariate Cox model (unadjusted); Model 2: adjusted for age, vasopressor use, sequential organ failure assessment score, simplified acute physiology score II score, glasgow coma scale score and elixhauser comorbidity index score; Model 3: adjusted for age, marital status, respiratory rate, heart rate, diastolic blood pressure, white blood cell, potassium, calcium, pH, creatinine, bicarbonate, hemoglobin, pulse oximetry-derived oxygen saturation, intensive care unit length, vasopressor use, sequential organ failure assessment score, simplified acute physiology score II score, glasgow coma scale score, elixhauser comorbidity index score, percutaneous coronary intervention and coronary artery bypass graft
- HR, hazard ratio; CI, confidence interval; Ref, reference; RDW, red blood cell distribution width; RAR, the ratio of the RDW to albumin; AMI: acute myocardial infarction
