HBV strains with complex SVs. Some HBV strains with complex SVs analyzed in this study are shown. Other HBV strains with complex SVs analyzed in this study are shown in Additional file 3: Figure S1A to AM. A nucleotide alignment of the reference sequence of V00866 and consensus genetic sequences of HBV/A to HBV/E is shown. a Complex SV pattern of strain No. 16, composed of insertion of unknown origin (X-1) and deletion. b Complex SV pattern of strain No. 20, consisting of insertion of unknown origin (X-2) and deletion. c Complex SV pattern of strain No. 25, composed of HNF1 binding site insertion and deletion. d Complex SV pattern of strain No. 59, consisting of insertion of a sequence complementary to part of box α in enhancer II and deletion. e Complex SV pattern of strain No. 37, composing of two duplications. f Complex SV pattern of strain No. 33, consisting of three insertions of partial HNF1 binding sites and duplication, categorized as class VI, highly complicated (four or more SVs) in the classification in Table 2
