Birth–Death Skyline reconstruction for HBV-A (A) and HBV-D (B). The graphs show the relationship between the reproduction number of infections (y axis) and the chronological time expressed in years (x axis). The curves indicate the mean, and the 95% HPD interval is shown by the green filling. Estimates were obtained using 29 HBV-A and 57 HBV-D sequences of a 650 nucleotide fragment of HBV S-gene from Yakutia
