Relative differences for binary outcomes (complications and readmission) reported as mean effects. 95% CI, 95% confidence interval.
P values are for the absolute difference statistic. Outcomes were estimated from a single model for all procedures. All models were adjusted for age, race, sex, and 27 Elixhauser categories for comorbidities: congestive heart failure, valvular disease, pulmonary circulation disease, peripheral vascular disease, paralysis, neurologic disorders, chronic pulmonary disease, diabetes with and without complications, hypothyroidism, kidney failure, liver disease, peptic ulcer disease, AIDS, lymphoma, metastatic cancer, solid tumor without metastasis, rheumatoid arthritis, coagulopathy, obesity, recent weight loss in last 6 months, fluid or electrolyte disorders, chronic blood loss anemia, other deficiency anemias, alcohol abuse, drug abuse, psychoses, depression, and hypertension.
