Note: Table shows summary statistics for control and treatment counties. In our analysis, control counties are counties where Medicaid managed care was not expanded that are contiguous with at least one county where Medicaid managed care was expanded. However, here we also show summary statistics for all counties in Texas where Medicaid managed care was not expanded. The significance stars show whether the control-treatment difference is statistically significant: ∗ p < 0.1, ∗∗ p < 0.05, ∗∗∗ p < 0.01. For more details, see Section III.
