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 i2 A GMV-based LOOCV predictive model significantly predicted individual differences in subtraction performance (r = 0.3506). → Zhang 2024

Cross-sectional predictive-modeling analysis of structural MRI and CMAT behavioral data from 130 children (grades 3-8). The subtraction model's observed-predicted correlation was significant, "sub- traction: r = 0.3506", and confirmed by two permutation testing approaches.

"For both the subtraction and multip lication predictive model, the correlation between observed and predicted scores was signi ficant (sub- traction: r = 0.3506, P =4 . 3 2×1 0−6; multiplication: r = 0.2824, P = 0.0011"
