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 quantile-based moderation for school quality (not controlled for school SES and parental SES), genetic variance is not declining linearly; only the first-versus-fourth quantile difference is significant (Wald test = 5.78, df = 1, p = .016). → Kim Stienstra 2024

q2 · i? · associational · r3

Multigroup (non-parametric) gene-environment interaction across quantiles of school quality (Supplementary Figs. 1–4), testing for threshold effects. The article reports "There is more genetic vari ance in the lowest-quality schools and less in the other four quantiles", with only the first-vs-fourth quantile Wald test significant.

"Only the difference in genetic variance between the first and fourth quantile is statistically signi ficant (Wald test = 5.78, df =1 , p = .016)."
