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)
