Mode 9 exhibited the most complex population pattern (Fig 7c). The most strongly-involved non-imaging measures were intelligence, education levels and occupational factors; additionally, some physical and dietary measures are involved, that may reflect socio-economic status as a latent factor (e.g., cheese intake or time spent outdoors in winter). Associated brain IDPs include task fMRI (with a negative weight, consistent with the sign of univariate associations, discussed above), followed by a range of functional and structural IDPs.
