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? In the event-related fMRI task, children showed significant Task-by-Time interactions for accuracy and reaction times, with larger improvements on Addition than Control problems. → Qin Shaozheng 2014

q3 · i? · associational · r2

Longitudinal event-related fMRI task performance in 20 children scanned twice; repeated-measures ANOVA revealed "Task-by-Time interactions for both accuracy and RTs (F(1,19)>4.97, Ps<0.04)", with larger Addition than Control improvements. No effect size is printed.

"Notably, we observed Task-by-Time interactions for both accuracy and RTs (F(1,19)>4.97, Ps<0.04) (Fig. S1c-d), with larger improvements in solving Addition (accuracy: t(19)=2.50, P=0.022; RTs: t(19)=5.63, P<0.001) than Control (accuracy: t(19)=0.68, P=0.50; RTs: t(19)=4.34, P<0.001) problems."
