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.

q2 i? Of 94 included studies, 79 were excluded from meta-analysis for critical risk of bias; the 15 synthesised studies were all non-randomised and all but one judged at serious risk of bias. → Dalgaard 2022

Dalgaard, N. T., Bondebjerg, A., Viinholt, B. C. A., & Filges, T. (2022). The effects of inclusion on academic achievement, socioemotional development and wellbeing of children with special educational needs. Campbell Systematic Reviews, 18, e1291. https://doi.org/10.1002/cl2.1291

q2 · i? · quant-synthesis · r3

Risk of bias assessment using ROBINS-I across the 15 studies in the synthesis; the review also reports no experimental studies with random assignment were found and 79 of 94 studies had critical risk of bias.

"The 15 studies, which could be used in the data synthesis, were all, except for one, judged to be in serious risk of bias."
