  1. Robust standard errors are in parentheses. Low-income status was determined at ≤ 138% of FPL
  2. Abbreviations. ACA Affordable Care Act, SNAP Supplemental Nutrition Assistance Program, β unstandardized beta coefficient, P p-value, SE standard error, FPL Federal Poverty Level
  3. aThe coefficient of ‘Time’ indicates trend (or slope) in the probability of SNAP participation in the low-income younger group before interruption/intervention
  4. bThe coefficient of ‘Interruption’ shows the level change in the likelihood of SNAP participation right after the interruption/intervention in the low-income younger group
  5. cThe coefficient of ‘Time∙Interruption’ indicates the trend (or slope) change in the probability of SNAP participation after the interruption in the low-income younger group
  6. dThe coefficient of ‘Treatment’ shows the level difference in the probability of SNAP enrollment before the intervention between the low-income older Medicare group and the low-income younger group
  7. eThe coefficient of ‘Treatment∙Time’ indicates the trend (or slope) difference in the probability of SNAP participation before intervention between the low-income older Medicare group and the low-income younger group
  8. fThe coefficient of ‘Treatment∙Interruption’ shows the level difference in the probability of SNAP enrollment between the low-income older Medicare group and the low-income younger group
  9. gThe coefficient of ‘Treatment∙Interruption∙Time’ indicates the change in slope difference in the likelihood of SNAP participation between the low-income older Medicare group and the younger with low incomes
