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.
q3 i0 On average, the pandemic depressed student achievement by around 0.19 standard deviations (Cohen's d = −0.18613). → Di Pietro Giorgio 2023

Di Pietro Giorgio. (2023). The impact of Covid-19 on student achievement: Evidence from a recent meta-analysis. Educational Research Review. https://doi.org/10.1016/j.edurev.2023.100530
q3 · i0 · quant-synthesis · r3
Random-effects robust-variance-estimation meta-analysis of 239 effect sizes from 39 studies; the precision-weighted mean effect size is Cohen's d = −0.18613 with 95% CI [-0.316, −0.055], significant at p = 0.0065.
"The RVE RE mean effect size turns out to be −0.18613 (SE = 0.0646, p-value = 0.0065, 95% CI [-0.316, −0.055])."
