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? Pairwise LDSC genetic correlations between nonword reading and word reading, and between nonword reading and spelling, exceeded 1.0, prompting exclusion of nonword reading from subsequent modeling. → Shiying Wang 2026

q2 · i? · associational · r2
LDSC pairwise genetic correlation analysis among the five reading-related traits and ADHD. The article attributes the estimates exceeding 1.0 to the unbounded LDSC estimator under sampling variation and insufficient effective sample size for nonword reading, and therefore excluded it from the SEM.
"Since genetic correlations between nonword reading and word reading, as well as between nonword reading and spelling, exceeded 1.0, nonword reading was excluded from subsequent Genomic SEM analyses."
Discussion¶
Related Claims¶
- A common genetic factor captures shared genetic influences across four reading-related traits and ADHD, with ADHD loading negatively and reading traits positively — related
- Non-word repetition (PWM) shows trait-specific genetic variance beyond the shared genetic factor — related
- Literacy, phonological awareness, oral language and PWM abilities share a large proportion of underlying genetic variation in unrelated youth — related
