Notes: 1The distribution of the occurrences is represented by (1) the number (percentage) of children within each one of four classes of prevalence, and (2) the median prevalence with inter-quartile range (IQR) and full range (min–max).
2The seven children with an observation period shorter than 90 days had their nominal observed number of occurrences multiplied by the inverse of the fraction of the 90 days they were observed, to make these observations comparable to the others.
