Table 6.

Sensitivity analysis comparing contiguous counties with and without Medicaid expansion. This table provides the proportion change in four outcome variables based on two-stage regressions for contiguous counties defined as physically adjacent counties in states with and without Medicaid Expansion. The first-stage regression is for the county rate of health insurance including the state-Medicaid-Expansion; the second stage is for the COVID-19 outcome variable. Two sets of regression results are reported, those where the dependent variable is the number of cases, the other where the dependent variable is the percentage of the population. Data are through mid-February 2021.
