Table 3 Varying sex-differences in odds of head injuries (given an injury), by injury mechanism (player-to-player contact)

From: Multifactorial examination of sex-differences in head injuries and concussions among collegiate soccer players: NCAA ISS, 2004–2009

Head injuries
(n = 860)
Men Women Women vs. Men
Other mechanisms Ref 2.41, 95% CI = [1.82, 3.20] 2.41, 95% CI = [1.82, 3.20]
Player-to-player contact mechanisms 5.99 95% CI = [4.56, 7.88] 7.35, 95% CI = [5.58, 9.69] 1.23, 95% CI = [1.03, 1.47]
  1. Measure of variability in sex-differences on additive scale: RERI = −0.05, 95% CI = [−4.08, 3.98]
  2. Measure of variability in sex-differences on multiplicative scale: Ratio of ORs = 0.508, 95% CI = [0.364, 0.711]
