  1. 1 T-Score; greater values correspond to elevated feature score
  2. 2 F-values for group with control of gender, nominal α
  3. 3 Effect sizes in comparison with controls (d 1 ; with control of gender) and in comparison with normative sample (d 2 ); Δ: at least moderate effect size of d1 and d2 suggesting potential reproducibility
  4. 4 T-values relative to controls
  5. 5 Effect size median.
