  1. *Only three patients had missing insurance data after imputation. The composition of health systems in the health system categorization of fee-for-services vs. integrated has been previously described [8]. Comorbidity was calculated using the Adult Comorbidity Evaluation-27 (ACE-27) index [11]. The cardiovascular comorbidities were collected as a part of the ACE-27. Some percentages may not sum to 100 due to rounding.
