a
Calculated by using Fisher exact t test (when cell size was small) and χ2 tests.
b
P value is for difference between whites and all other racial/ethnic minorities combined because of small numbers in each race/ethnicity category.
c
P value is for difference between urban and nonurban residence only. Rural-Urban Commuting Area codes classify US census tracts by using measures of population density, urbanization, and daily commuting. One Medicaid recipient in the sample was missing data on residence.
