The model-predicted difference in executive function z-score (y-axis) associated with reallocations of time towards or away from each time-use behaviour (displayed in the header of each panel) in 15-minute increments from the reference mean time-use composition. Purple lines represent participants with greater than the sample mean total grey matter volume (‘Upper’); orange lines represent participants with less than the sample mean total grey matter volume (‘Lower’). Shading represents 95% confidence intervals. Mean total grey matter volume (corrected) in the ‘upper’ group = 611.4 ± 10.6, range = 596.7, 647.9. Mean total grey matter volume (corrected) in the ‘lower’ group = 580.7 ± 12.9, range = 519.8, 596.7
