The bottom two rows show the estimated difference in utilization between the treatment groups and the CONTROL group. The UNINS have lower utilization than the CONTROL group both before (−0.0207) and after (−0.0182) the introduction of 30 Baht. This implies a difference-in-differences estimate of 0.0025 ( p > 0.10), which suggests the 30 Baht program had a modest but statistically insignificant impact on inpatient utilization.
