P-value for difference in incidence of mortality for fistula vs graft within race/ethnicity group compared to difference in incidence of mortality for fistula vs graft within Whites

Predictive margin adjusted for age and its square, sex, index year, index month, total covered charges from outpatient, inpatient and carrier files in the year preceding index fistula/graft creation date, inpatient setting for the index fistula/graft creation and all co-morbidities available from the Chronic Condition Data Warehouse (except chronic kidney disease), community contextual factors and hospital referral region.
