Figure 4.

Subcortical volumes based on prior concussion and association with years of primary sport participation in contact sport athletes only. (A) Shown are raincloud plots of subcortical volumes in participants without (0) and with at least one prior concussion (1+). (B) Shown are scatter plots of years of primary sport participation vs. subcortical volume in contact sport athletes without (0) and with at least one prior concussion (1+) with 95% confidence intervals. The mean subcortical volumes across all visits are displayed for individual participants.
