Fig. 3From: Is the allocation of medical and health resources effective? Characteristic facts from regional heterogeneity in ChinaThe efficiency means of PMHE in four regions from 2005 to 2017. a, Comparison of efficiency means of PMHE for four regions from 2005 to 2017 between stage 1 and stage 3. a A-D, the comparison of the efficiency values of the stage 1 and stage 3 in the east, the central, the west and the northeastern. b, the mean of PMHE with 95% confidence interval and displayed the coefficient of variation in the four regions. b A, the mean efficiency value of PMHE and its 95% confidence interval at stage 3 in the East. b B, the trend of the coefficient of variation and the robust coefficient of variation at the third stage in the East. b C, the mean efficiency value of PMHE and its 95% confidence interval at stage 3 in the Central. b D, the trend of the coefficient of variation and the robust coefficient of variation at the third stage in the Central. b E, the mean efficiency value of PMHE and its 95% confidence interval at stage 3 in the West. b F, the trend of the coefficient of variation and the robust coefficient of variation at the third stage in the West. b G, the mean efficiency value of PMHE and its 95% confidence interval at stage 3 in the Northeast. b H, the trend of the coefficient of variation and the robust coefficient of variation at the third stage in the NortheastBack to article page
