Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? The Likelihood Ratio Test showed significant difference between dysgraphia and non-dysgraphia classification across groups (p <0.001), with dysgraphia most frequent in GI (80%) and GV (60%) and least in GIII (10%). → Capellini 2017

q2 · i? · associational · r1
Handwriting quality was rated with the Lorenzini Dysgraphia Scale (dysgraphia at 50% of total score). Table 6 reports the group contrast at p <0.001; "80% of the students of GI were considerate with Dysgraphia, 10% of GIII and 60% of GV".
"the results showed that there was significant difference between the classification of Dysgraphia and Non- dysgraphia between the groups. A c-cording to this table, 80% of the students of GI were considerate with Dysgr a-phia, 10% of GIII and 60% of GV"
Discussion¶
Related Claims¶
- 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
- No significant difference was found between grade groups in the classification distribution of VMI, VP and MC performance levels — related
- Acquisition of visual perception, motor coordination and visual-motor integration does not progress linearly across grades 1 to 5 — related
- First-grade students show inferior visual-motor integration, visual perception and motor coordination performance compared with the other grade groups — related
