Percentage difference was calculated using the formula $\frac{o b s e r v e d v a l u e - p r e d i c t e d v a l u e}{p r e d i c t e d v a l u e} \times 100 %$ , where the predicted value was estimated based on the 2016-2019 monthly number of healthcare occasions using the autoregressive error models.
