a, the model includes: age, gender, household income, service payer, Charlson comorbidity index score, hospital volume, and hospital teaching status (N=11,365); b, the model includes surgeon volume in addition to the above factors. The sample size for this model is (N=5,438). aOR, adjusted odds ratio; CI, confidence interval; CCIS, Charlson comorbidity index score; yr, year.
