Values expressed as odds ratios (OR) and 95% CIs

^*Previous models adjusted for sex, age, race/ethnicity, urban/rural status, state of residence, and ZCTA-level poverty

^†Updated model adjusted for the same variables as previous model, plus distance to provider

^§Defined as the combination of “Native American/Alaskan,” “>1 race (Hispanic), “>1 race (non-Hispanic),” and “Hawaiian”
