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 i3 On the delayed post-test two weeks after treatment, the experimental group retained and slightly increased its improvement while the control group remained nearly unchanged, with a large effect size (d = 4.62). → Ahmed Ali Saleh Al Ajmi 2015

q2 · i3 · causal · r1
Independent samples t-test on the delayed post-test, administered unannounced two weeks after treatment. Experimental group M = 8.08 (SD = 1.75) versus control M = 1.48 (SD = 1.08); "the effect size was large (d= 4.62)".
"The scores for the delayed post-test also showed a significant difference in the experimental group scores as they remained higher, with a slight increase, than the immediate post-test scores (M =8.08, SD =1.75) while the control group’s scores showed no noticeable increase (M=1.48, SD=1.08), t(48)=16.001, p=.000, two-tailed), and the effect size was large (d= 4.62)."
