The “treat × 2–4 years exposure” coefficient represents the differential effect of treatment for respondents exposed to treatment for 2-4 years, compared to the effect for those exposed for less than 2 years. The uninteracted treatment coefficient presents treatment effects for respondents who were exposed to treatment for less than 2 years. Additional controls (in columns 2, 4, and 6) include gender, age, and survey round, and all interactions of these variables.
