| Significant functional delay, ASD | 3,839 | 29.6 | 0.18 | 29.3 | 30.0 |
Note. DCD-Q final scores worsened with increasing SC impairment, increasing RB severity, decreasing cognitive ability, decreasing language ability, and decreasing functional ability, with each category significantly differing from the other (ps < 0.0001).
