The constituent ratio of HBV genotypes and genotypic mutations among CHB patients over the past seven years. (a) Dynamic changes in the constituent ratio of different genotypes among CHB patients over the past seven years; Percentage = cases of CHB patients with genotype B(C) per year/cases of the total number of CHB patients per year. (b) Dynamic changes in the constituent ratio of genotypes among CHB patients with genotypic mutations over the past seven years. Percentage = cases of genotype B(C) patients with genotypic mutations per year/cases of the total number of CHB patients with genotypic mutations per year.
