Note: Quarter −1 corresponds to event months −3, −4, and −5 relative to the quarter of application decision. The income eligibility cutoff is 350% of FPL. Column 1 shows means for the baseline sample with income between 150% and 550% of FPL; columns 2 and 3 show means for applicants within 100 percentage points of the 350% FPL threshold. Columns 4 and 5 report coefficient estimates and p-values on an indicator for income below the 350% of FPL threshold from our baseline regression discontinuity specification (equation 1).

^aCalculated for the 12 months prior to program application.

^bThe insurance coverage variables are indicators for being insured in all months of quarter −1

^cWinsorized at the 95th percentile.
