Results show odds ratios with 95% confidence intervals from logistic regression models. Model 1 is adjusted for age, sex, and race; model 2 for age, sex, race, procedures, diagnoses, and DRG weights; model 3 for age, sex, race, procedures, diagnoses, DRG weights, and laboratory values including estimated glomerular filtration rate.
