The sentences

highly significantp < 0.001actually significant

The log likelihood ratio tests revealed that all models were highly significant compared to a single level model (Working Memory: χ 2 = 83.34, p < 0.001; Maths: χ 2 = 131.12, p < 0.001; Reading: χ 2 = 91.03, p < 0.001), indicating a substantial amount of variance attributable at the individual/upper level.

borderline significancep = 0.044actually significant

The only exception was for IQ, which was higher for the MetaCogmed group compared to the control group at borderline significance ( p = 0.044).

borderline significantp = 0.059so close (0.05 < p ≤ 0.1)

This difference was statistically significant for the Cogmed group ( p = 0.019) and borderline significant for the MetaCogmed group ( p = 0.059).
