Comparison of M204, A181 and N236 mutation patterns in genotypes B and C. (A) The prevalence of mutations associated to M204I or V. The asterisk on the left of the mutation sites indicate significant differences in the mutations associated to M204I or V. The arrows indicate significant differences in M204 mutation patterns between genotype B and C. (B) Main mutation patterns of A181 and N236.*P < 0.05; **P < 0.01.
