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? Information and Similarities scaled scores increased significantly from CI-E to CI-HS, indicating growth exceeding one year's growth in a year relative to hearing age-mates. → Geers Ann E. 2011

Longitudinal comparison of the same 112 students tested at ages 8-9 (CI-E) and in high school (CI-HS); repeated-measures F tests on WISC-III subtest scaled scores, with Information F (1, 90) = 52.9 and Similarities F (1,111) = 38.9, both p <.0001. Percent within expectation rose from 64% to 81% (Similarities) and 49% to 86% (Information).
"The mean Information scaled score increased from 6.7 (SD = 3.9) at CI-E to 9.3 (SD = 3.1 at CI-HS [F (1, 90) = 52.9, p <.0001] and the Similarities scaled score increased from 7.6 (SD= 3.5) at CI-E to 9.4 (SD = 3.2) at CI-HS [F (1,111) = 38.9, p<.0001]."
