Subclaims¶

q2 i3 A significant group × ISL change interaction was found on day-2 WMV underlying the left precentral gyrus: the TD group showed a negative correlation (r = −0.501, p = 0.034) while the DD group showed no correlation (r = 0.235, p = 0.364). → Olivo 2024

q2 · i3 · associational · r2

Voxel-wise whole-brain correlation analysis in CAT12 with group as moderator, on the 17 DD and 18 TD children; the interaction cluster of 744 voxels under the left precentral gyrus reached "p FWE-corr = 0.006; F = 32.13".

"In particular, while a negative correlation was present in the TD group ( p = 0.034; r = −0.501), no correlation was observed in the DD group (p = 0.364, r = 0.235)"
