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 The review found no clear evidence of an immediate effect of linguistic comprehension instruction on generalized reading comprehension outcomes in the trials it included: the pooled posttest effect was close to zero and not significant (g = 0.05, 95% CI [−0.01, 0.12], p = .13, 16 effect sizes), which does not show the true effect is zero. → Rogde K 2019

Meta-analytic synthesis across the 43 included RCTs and QEs. The review reports "no clear evidence of effect" on general reading comprehension outcomes. Its Table 6 gives the immediate (posttest) pooled estimate for reading comprehension as g = 0.05, 95% CI [−0.01, 0.12], p = .13, from 16 effect sizes (9,758 treatment, 8,045 control), with heterogeneity (I² = 59.87); equivalence was not tested, so this is an absence of a detected effect rather than evidence of none.

"However, there was no clear evidence of effect of linguistic comprehension instruction on general reading comprehension outcomes from the type of trials included in this review."
