Data in table: HR (95%CI) value. Outcome variable: mortality. Exposed variables: neutrophil. Model I adjusted for: age and sex. Model II adjusted for age, sex, injury mechanism, fracture classification, aCCI, hypertension, CHD, arrhythmia, ischemic stroke, cancer, dementia, COPD, hepatitis, time to admission and surgery, treatment strategy, operation time, and infusion.
