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? Across latent factors for the ability domains, all but one pathway from PGS to the pre-test or latent difference score was small and statistically nonsignificant, and PGS × age interactions were also nonsignificant. → Cherry Youn 2022 q2 i? In contrast, pathways from age to the pre-test factor model and to the latent difference score were consistently significant. → Cherry Youn 2022 (2)

q2 · i? · associational · r2

Latent difference score modeling in Mplus (version 8) of the three ability-domain factors, using the full sample with maximum-likelihood estimation, measurement invariance across time, and age group and PGS covariates. The article reports pathways "were small in magnitude and statistically nonsignificant".

"all but one pathway from PGS to the pre- or the latent difference score were small in magnitude and statistically nonsignificant"

q2 · i? · associational · r2

Same LDSM analysis: the article reports "consistently significant pathways (1) from age to the pre-test factor model and (2) from age to the latent difference score", while PGS × age group interactions were nonsignificant.

"In contrast, we found consistently significant pathways (1) from age to the pre-test factor model and (2) from age to the latent difference score."
