a
Authors’ analysis of the 2011-2016 National Cancer Database. CI = confidence interval; DD = difference in difference; ME = Medicaid expansion; ppt = percentage points.
b
Adjusted model: regression models also adjusted for age, sex, race or ethnicity, zip code–level income, residence metropolitan statistical area status, and linear time trends as well as state adjusted as a random effect.
c
P values were calculated from linear probability regression models and reflect 2-sided test of statistical significance.
