Adjusted OR for in-hospital death associated with ESRD status in an elderly cohort of ICU patients

Adjustment Model	OR for Death Associated with ESRD (95% CI)	Global Model P Value	Model AUROC
Model 1 (case mix)	2.24 (1.67 to 2.98)	<0.0001	0.58
Model 2 (illness severity)	0.85 (0.57 to 1.25)	<0.0001	0.87
Model 3 (case mix and illness severity)	0.82 (0.55 to 1.23)	<0.0001	0.89

Model 1 is adjusted for age (years), gender, location (community versus tertiary hospital), diabetes, cardiovascular disease (presence of coronary artery disease or congestive heart failure), peripheral vascular disease, and stroke. Model 2 is adjusted for APACHE II, sepsis (present or absent), mechanical ventilation (present or absent), surgical status (surgical or nonsurgical), number of failed organs (≤2 versus ≥3), temperature (<36.5, 36.5 to 38.5, >38.5°C), heart rate (<60, 60 to 100, >100 bpm), mean arterial pressure (mmHg), respiratory rate, hematocrit (< or >0.3), white blood cell count (cells/mm³), serum sodium and potassium (mmol/L), serum creatinine (μmol/L), and Glasgow coma scale (<7, 7 to 12, >7). Model 3 is adjusted for all covariates in model 1 and 2. CI, confidence interval.
