^*Beta coefficient represents change in age-adjusted mortality per 100,000 population per unit change of each variable. Variables not included in the final model because they were not significant (p>0.1) in univariable or multivariable models included: median household income, Black race, unemployment, number of gastroenterologists and primary care physicians per 100,000 population

^†Based on 2010 data among those living at or below 138% of the federal poverty level

^‡Hispanic ethnicity modeled as a categorical variable due to the distribu8on of the data
