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 i? 45 of 126 children (35%) met the dual-informant CADS cutoff of 1 SD or more above the mean, and identified versus nonidentified children differed significantly on five of 10 baseline measures. → Feil 2016
