The three subgroups with significant differences between responders and non-responders are marked. (GMFCS Gross Motor Function Classification System; ID Intellectual Disability; ASD Autism Spectrum Disorder; ADHD Attention-Deficit/Hyperactivity Disorder)
aSignificantly higher proportion in the non-responder group of 32 children (p = 0.046)
bSignificantly lower proportion in the non-responder group of 32 children (p = 0.025)
cSignificantly higher proportion in the non-responder group of 32 children (p = 0.015)
