aWilks’ λ is the product of the values (1—Canonical R2) for the current canonical variate and all variates below it. Therefore, lower values for Wilks’ λ represent a greater proportion of variance shared between the variable sets across all canonical variate functions.

bN-BM, number of biomarker variables included in a given modality.

cAs the negative symptom—DTI construct did not meet even exploratory significance, subgroup comparisons were not performed.
