Infant and child groups were compared using a two-tailed Fisher’s Exact Test for categorical data and the Wilcoxon rank-sum test for continuous data. There was no significant difference between infants and children for any clinical variable. Resistant bacteria were cultured and clinical data were collected in a previously published study [19].
