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.
q3 i1 Bullied children had thinner cortices than non-bullied children in the left hemisphere, left banks of STS, left middle temporal gyrus, left precentral gyrus, and right rostral middle frontal regions. → Menken Miriam S. 2023

q3 · i1 · associational · r2
LMM analysis of cortical thickness in the matched ABCD sample across two visits. The article reports thinner cortices in the five named regions in bullied children with the printed d values and p-values.
"bullied children had thinner cortices in the left hemisphere (d= −0.39, P = 0.041), left banks of superior temporal sulcus (STS) (d= −0.43, P = 0.038), left middle temporal gyrus (d= −0.48, P = 0.009), left precentral gyrus (d= −0.48, P = 0.006), and right rostral middle frontal regions (d= −0.36, P = 0.034)"
Discussion¶
Related Claims¶
- Bullied preadolescents show larger cortical volumes in left entorhinal, left superior parietal, and right fusiform regions than matched non-bullied peers
- Bullied preadolescents score lower than matched non-bullied peers on reading, processing speed, and inhibitory control/attention over two years — related
- Larger right fusiform surface area in bullied children partially suppresses the negative effect of bullying on crystallized composite and vocabulary scores — related
- Sex moderates bullying-related cognitive and brain differences, with effects in boys and girls appearing in different regions and tasks — related
