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? After pretest adjustment, RHS students' grade point average (0.26, 95% CI [‐0.04, 0.56]), truancy (0.01), and alcohol use (0.23) were similar to comparison students, with confidence intervals crossing zero. → Hennessy E. A. 2018

q2 · i? · quant-synthesis · r1

The review's Results section reports pretest‐adjusted effect sizes from the single included quasi‐experimental study: GPA, truancy, and alcohol use did not differ between RHS and comparison students, with all three confidence intervals including zero. Equivalence was not formally tested.

"students in the RHS condition reported levels of grade point averages (= 0.26, 95% CI [‐0.04, 0.56]), truancy (= 0.01, 95% CI [‐0.29, 0.31]), and alcohol use (= 0.23, 95% CI [‐0.07, 0.53]) similar to participants in the comparison condition."
