n/I = number of individual children exhibiting a particular code in each episode (out of 70);

M = arithmetic mean; SD = standard deviation

^*p < 0.05,

^**p < 0.01,

^***p < 0.000.

Note: Means with differing superscripts are significantly different from each other as assessed using simulation based post hoc tests at p < 0.05.
