q2 i? No associations were observed between left STG/pre-CG session changes and reading fluency or pre-test slope, and no pre-CG interactions reached significance. → Romanovska 2022

q2 · i? · associational · r2

Mixed regression null results from the longitudinal fMRI sample: session × covariate interactions for baseline age, reading fluency, recalibration effect and pre-test slope were all non-significant in the lateral inferior pre-CG. The discussion states "No links with children ’s reading fluency or phonological processing (pre-test slope steepness) were observed."

"None of the interaction effects reached signi ficance for the left lateral inferior pre-CG (all F ≤ 4.030)."
