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? Children who performed better in reading comprehension had thicker cortex in the left parahippocampus and right calcarine fissure, independent of age, gender and performance IQ. → Xia Zhichao 2018

q2 · i? · associational · r2
Whole-brain vertex-wise regression (n = 21) reported in the Results section. The authors state that "children aged 10-12 years who performed better in reading comprehension had a thicker cortex in these two regions." No effect size was printed.
"Two significant clusters correlated with sentence reading comprehension independent of age, gender and performance IQ (Table 3, Figure 1B). These clusters were in the left parahippocampus (LPHP: x, y, z = -27, -1, -27) and right calcarine fissure (RV1: x, y, z = 9, -104, 5)."
Discussion¶
Related Claims¶
- The authors hypothesize that brain-reading cortical thickness correlations are positive in early reading acquisition and negative at later, consolidated stages — related
- The word-reading and comprehension cortical regions are specific to their respective reading level: cross-level correlations were nonsignificant after FDR correction — related
- In Chinese children aged 10-12, oral word reading efficiency is positively correlated with cortical thickness in the LSTG, LITG, LSMG and RSTG — related
- For sentence comprehension regions, LPHP thickness is correlated with morphological awareness and RV1 thickness with orthography-semantic mapping — related
