Total counts from the rural and urban income quintiles do not equal the total count of angiograms because some incomes could not be found.
*Unless otherwise indicated.
†Percentages are calculated for rural and urban areas separately.
‡Statistical comparisons were not conducted on each condition used in the Charlson Comorbidity Index Score calculation.
