CI = confidence interval; HR = hazard ratio. Adjusted I for age, gender, and ethnicity. Adjusted II for age, ethnicity, time in hospital, first care unit, QSOFA, LODS, SAPSII, mean corpuscular volume, mean corpuscular hemoglobin, white blood count, red blood cell, blood urea nitrogen, hematocrit, creatinine, infection, liver disease, blood loss anemia, deficiency anemias, and weight loss. Reference group: RDW level 12.1-13.9%.
