q2 i? Likelihood Ratio Tests on the standardized classification categories (very low to very high) showed no significant between-group difference for VMI (p = 0.468), VP (p = 0.246) or MC (p = 0.733), and no group reached the very high classification. → Capellini 2017

Table 5 gives frequency and percentage of standardized performance classifications per group, analyzed by Likelihood Ratio Test. The article reports "no significant difference between the classification of VMI, VP and MC between the groups"; equivalence was not tested.

"the results showed that there was no significant difference between the classification of VMI, VP and MC between the groups. In addition, none of the groups received the classification very high in any tests"

• Dysgraphia classification differs significantly across grade groups, with 80% of 1st graders, 10% of 3rd graders and 60% of 5th graders classified with dysgraphia — related
• First-grade students show inferior visual-motor integration, visual perception and motor coordination performance compared with the other grade groups — reports the opposite
• Visual-motor integration was the lowest-scoring ability and motor coordination the best-performing ability in every grade group — related
• Acquisition of visual perception, motor coordination and visual-motor integration does not progress linearly across grades 1 to 5 — related
• Only in the 5th-grade group were moderate positive correlations found, between visual-motor integration and motor coordination (r = 0.748) and between visual perception and dysgraphia classification (r = 0.643) — related
