Fig 1.
Association of SARS-COV-2 mortality rate ratios (95% confidence intervals) by median household income quartiles, for counties in Medicaid (gray diamond) and non-Medicaid expansion states (orange diamond), referent = Quartile 4.
In fully adjusted analyses, median household income quartiles were associated with COVID-19 mortality only in counties within non-Medicaid-expansion states (orange diamond), but there were no significant differences in COVID-19 mortality risk by income quartiles in counties within Medicaid expansion states (gray diamond).
