  1. &To maintain mutual exclusivity between comorbidities and outcomes, the ICD-9-CM diagnosis codes used to define complications were removed from the Elixhauser algorithms. The following ICD-9 codes were removed: 557.9 (peripheral vascular disease), 586 (unspecified renal failure), and all codes for valvular heart disease
  2. *Standardized differences are reported as absolute values
