Dose–Response relationships between head impact exposure and salivary biomarkers. (a) Modeled relationship between post-tournament salivary S100B and the number of head impacts sustained during the tournament after adjustment for pre-tournament S100B (n.s.). (b) Modeled relationship between post-tournament salivary S100B and wCHI sustained during the tournament after adjustment for pre-tournament S100B (n.s.). (c) Modeled relationship between post-tournament salivary NfL and the number of head impacts sustained during the tournament after adjustment for pre-tournament NfL (RR = 1.151; 95% CI 1.031, 1.285; p = 0.025). (d) Modeled relationship between post-tournament salivary NfL and wCHI sustained during the tournament after adjustment for pre-tournament NfL (RR = 1.008; 95% CI 1.002, 1.013; p = 0.014). Dashed lines represent 95% Confidence intervals.
