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? In a parallel model replacing ADHD with anxiety disorders, anxiety did not load significantly and model fit was poor, and leave-one-reading-trait-out analyses left model fit and the ADHD loading stable. → Shiying Wang 2026

q2 · i? · associational · r3
Sensitivity analysis in Genomic SEM fitting a parallel model in which ADHD was replaced with anxiety disorders from the PGC GWAS. The article reports anxiety "did not load significantly and model fit was poor (SRMR >0.1)"; leave-one-reading-trait-out models kept fit good and the ADHD loading stable. No effect size is printed.
"In the model including reading and anxiety disorders (Supplemental Note 2), anxiety disorders did not load significantly and model fit was poor (SRMR >0.1), indicating that the common factor model is specific to reading and ADHD."
Discussion¶
Related Claims¶
- The common factor shows significant genetic correlations with six psychiatric disorders and six behavioral traits, strongest with PTSD (rg = -0.47) and educational attainment (rg = 0.74) — related
- A common genetic factor captures shared genetic influences across four reading-related traits and ADHD, with ADHD loading negatively and reading traits positively — related
