a positive trendp = 0.069
Although not statistically significant, there was a positive trend between mTBI participant’s CogSport one-back scores, and both left hippocampal volume [ R (23) = 0.37, p = 0.069], and right hippocampal volume [ R (23) = 0.31, p = 0.137] (see Supplementary Figure 4 ). 3.4 Cortical thickness findings Vertex-wise analysis revealed a significant cluster of lower cortical thickness in the right lateral orbitofrontal cortex in recently concussed footballers compared to controls (peak p = 0.013; see Supplementary Figure 5 ).
