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? Fitting linear, logarithmic, and exponential growth models with EAPGS as a predictor of random-effect parameters revealed substantial individual variability in shape and rate of learning but no statistically significant EAPGS associations. → Cherry Youn 2022

q2 · i? · associational · r2
Nonlinear growth curve models (NLMIXED in SAS) fitted to cognitive performance across 100 days for 131 participants, with EAPGS entered as a predictor of all random-effect parameters. The article reports "no statistically significant associations between the EAPGS and this variation".
"Results indicated substantial variability in the shape and rate of learning. However, there were no statistically significant associations between the EAPGS and this variation."
