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 i3 The experimental group's mean VAT score rose significantly from pre-test to post-test, with a large effect size. → Manal Mohamed Khodary 2017

Within-group pre-post comparison for the VSSPlus experimental group (n = 40) over the 11-week treatment; the difference was "statistically significant (t = 20.03, p < 0.05)" with an effect size of 0.911, considered large.
"the mean score of the experimental group on the pre VAT was 23.92 with a standard deviation of 3.40, while its mean score on the post VAT was 37.92 with a standard deviation of 2.38"
