Time required and success rates of IOI with BIG

	Time required Mean ± SEM (sec)	Success rate
Adult	29.1 ± 0.63	93% (93/100)
Pediatric	28.7 ± 0.60	94% (94/100)
Infant	29.3 ± 0.65	84% (84/100)*

The time required for IOI with BIG was compared using one-way analysis of variance (ANOVA) followed by Fisher's PLSD (Fisher's Protected Least Significant Difference). The success rates of IOI with BIG were compared using the chi-square test.

There was no difference in the time required for performing IOI with BIG among the different leg models. The success rates of IOI with BIG were significantly lower in infant leg models when compared to adult and pediatric leg models.

*p < 0.05 in chi-square test.
