IL6 and concussion: Prior to corrections for multiple comparisons, IL-6 was significantly different between TBI mechanism groups, (F(1, 459) = 3.73, p = 0.025, q = 0.075, ηp2 = 0.016), pairwise comparisons revealed that individuals with blast-related mTBI had higher IL-6 concentrations compared to those with no history of mTBI (p = 0.018) and blunt-related mTBI (p = 0.015).
