Summary of ROIs identified in control athletes that show significant effects on c₁ for demographic factors of age, sex or history of concussion (conc.hx.). Standardized effect sizes are reported in terms of BSRs. Significant effects are noted with “*” (FDR = 0.05 threshold). Brain regions are defined based on the BNA
