Note: Omitted year for baseline comparison is 2005, when the NHI payment policy was changed. Numbers in parentheses are z-values. Likelihoods are estimated from odds ratio based on the results from the mixed model. Likelihoods estimated by the logit model generate similar results; thus, they are not reported due to space considerations. Full regression results are not reported since all three models generate comparable results as in Table 3. **, *** represent the 0.05, and 0.01 statistical significance level, respectively.
