^*The columns show the results of comparisons of means with the Mann–Whitney independent samples U-test between participants with CIs and NH 6-year olds. ^∗∗The columns show the results of comparisons of means with the Mann–Whitney independent samples U-tests between NH 6- and 13-year-olds. ^∗∗∗The comparison was non-significant after adjusting for multiple testing. The medians and sample sizes that were used in the analyses can be found in Table 3.
