Subclaims¶
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? Fourteen intervention children (54%) responded or improved versus two control children (11%), χ2 = 8.99, p = .002, OR = 9.9 [1.9, 51.9]. → Feil 2016

q3 · i? · causal · r2
Responder analysis using Jacobson and Truax's Reliable Change Index with a CADS cutoff at T = 59, based on teacher report in the 45-child subsample (26 intervention, 19 control). The article reports "OR[95% CI] 5 9.9[1.9, 51.9]"; responding children averaged a 2 SD improvement in CADS scores. No standardized effect size (d, g, r) is printed for this contrast.
"Overall, 14 intervention children (54%) either responded or improved after participating in the PFS intervention compared to two children (11%) in the control condition ( χ2 5 8.99, p 5 .002, OR[95% CI] 5 9.9[1.9, 51.9])."
