Fig 4. Difference-in-differences (DID) estimates for each care level and their 95% confidence intervals.

Fig 4

Confidence intervals are calculated by clustered robust standard errors clustered by municipality. All DID estimates are estimates for βτ in Eq (1). The unit of “benefit” is 1,000 points (10,000 JPY or around 100 USD in standard areas).
