The regression model ( Table 4 ) provided a highly significant fit for the Executive Function index; the proportion of variance explained was 0.6 (F = 19.8, p<0.00001).

Overall, whole brain volume acted as a better single predictor of cognitive performance than grey matter volume, and in the multi-predictor model a strong independent association was observed between brain volume and processing speed, but this did not reach statistical significance for executive functioning.
