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.

q4 i0 For the subset of comparisons assessing procedural knowledge, the pooled effect size was near zero and not statistically significant, indicating no detected PS-I advantage for procedural skills. → Tanmay Sinha and Manu Kapur 2021

Subgroup of the same three-level meta-analysis restricted to the 51 of 166 comparisons assessing procedural knowledge. The pooled effect was "Hedge’s g = −0.03, p = .7384, 95% CI [−0.20, 0.15]", a printed effect size of negligible magnitude; equivalence was not tested.

"For the n = 51/166 comparisons assessing procedural knowledge, results suggested the pooled effect size for procedural knowledge to be Hedge’s g = −0.03, p = .7384, 95% CI [−0.20, 0.15]."
