Fig. 2

Distribution of blastocyst quality in early- and late-cleaved groups. The figure demonstrates the proportion of early blastocysts (5), blastocysts (6), and expanded blastocysts (7) at grades A, B and C and the grade A hatched blastocysts (8) in the early- (white bars) and late-cleaved groups (black bars). The values are presented as the percentages of the embryos within each group. The numbers above the bars show the precise percentage of the embryos from each category
