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? Boys scored significantly higher than girls on EA in the lowest, low and high SES groups, but not in the highest SES group. → Eveline L. de Zeeuw 2019

q2 · i? · associational · r3

Likelihood-ratio tests of sex differences in mean EA within each of four SES groups in the Dutch twin sample; boys scored higher in three groups (e.g., p < 0.001 in low and high SES) but not in the highest SES group (p = 0.346).

"Boys had a signi ficantly higher EA than girls in the lowest ( Δ−2LL = 7.0, Δdf = 1, p = 0.008), low ( Δ−2LL = 26.7, Δdf = 1, p < 0.001) and high ( Δ−2LL = 19.5, Δdf = 1, p< 0.001) SES group, but not in the highest ( Δ−2LL = 0.9, Δdf = 1, p = 0.346) SES group."
