Scatter Plot from Scientific Research

The blue dots show the observed LOSeg, in June 2009, the observed LOS was 9.26 days. The red solid line shows the LOS estimated by the complete reform model (negative binomial regression modelling)eg, in June 2009 the complete reform model estimated that the LOS was 8.68 days. The red dashed line shows the counterfactual that estimated LOS if no reform had occurred (negative binomial regression modelling)eg, in June, 2018, the counterfactual estimated that the LOS was 6.60 days. However, the complete reform model estimated that in June 2018 the LOS was 7.43 days (red solid line). This finding suggests that the LOS estimated by the complete reform model in the post-reform period is greater than that estimated by the counterfactual. LOS=length of stay.
