IQR indicates interquartile range.
a
According to χ2 tests.
b
Denominators for these percentages are as follows: n = 220, <1 year; n = 3980, 1–9 years.
c
Denominators for these percentages are as follows: n = 77, <1 year; n = 157, 1–9 years.
d
According to Student's t test.
e
According to Wilcoxon rank test.
f
Examples of other transfers include transfer to skilled nursing facility or intermediate care. One child with noninflicted injury who left against medical advice and 1 child from each group with unknown disposition were excluded from the analysis because of small numbers.
