Note. CI = confidence interval; post = after vs before Medicaid expansion; SNAP = Supplemental Nutrition Assistance Program enrollee; treated = live in a Medicaid expansion state. Results shown are from difference-in-difference linear probability models.
a
Expressed as percentage of study population experiencing VLFS.
b
Treated × post is the change in VLFS in expansion states relative to nonexpansion states before vs after the 2014 Medicaid expansion.
