Atypical connectivity in the cortico-striatal network in NF1 children and its relationship with procedural perceptual-motor learning and motor skills

Table 1 Demographic and psychomotor characteristics of NF1 and typically developing children (TD)

	NF1 (n = 17)	TD (n = 18)	Statistic	p-value
Demographic characteristics
Mean age in months (SD; range)	116 (20.23; 96–171)	121 (14.65; 96–150)	117.0	0.241
Sex ratio (male/female)	0.41	0.55	131.0	0.413
Psychomotor characteristics
Mean M-ABC score (SD)	16.07 (19.56)	50.51 (26.35)	40.0	< 0.001

Note that NF1 children had significantly lower M-ABC scores, and nine of them had scores below the 15th percentile. The Mann-Whitney U test was used for the M-ABC score, as it was not normally distributed. The results were presented as means (standard deviation)
