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 i0 On the Pre-CTOPPP Elision subtest, differences between the Bright Beginnings group and the comparison group were not statistically significant, with an effect size of -0.08 favoring the comparison group. → phon-1

q3 · i0 · causal · r2
The PCER Consortium (2008) randomized trial (14 classrooms, 198 children) assessed phonological processing with the Pre-CTOPPP Elision subtest. Appendix C.3 reports an effect size of -0.08, improvement index -3, p > 0.05; the WWC characterizes the finding as an indeterminate effect, rating the domain no discernible effects.
"The authors reported that differences between the Bright Beginnings group and the comparison group were not statistically significant on this measure."
