Correlation between resolution rate and CBD size in (A) all-inclusive patients, (B) infant, and (C) children group. The regression curve and first-order differential plot are shown in all three groups. The CBD size corresponding to the slope equal to zero is determined as the starting point of the resolution rate decline. The CBD size was 3.24 mm in (A) the all-inclusive patient group and 2.51 mm in (B) the infant group. No slope and CBD size interval exist in (C) the children group.
