∗Odds ratios were determined from multivariable models, adjusting for age (continuous), race, sex, payer type, income, diagnosis-related group, and BHCS facility at which care was provided.

†Income grouping was based on the Texas state ZIP code and income data: low, ≤$35,324; medium, $35,325–49,649; high, >$49,649. Patients for whom ZIP code data were unavailable were excluded from the analysis.
