Results of Poisson regression models identifying the risk factors for the 5 most prevalent injuries in the National Football League: (A) concussion, (B) knee injury, (C) ankle injury (the significance of the risk of ankle injury associated with time zone [TZ] change was P < .05; however, this failed to reach significance after false discovery rate [FDR] adjustment), (D) hamstring injury, and (E) shoulder injury. IRR, incidence rate ratio; Ref, reference; TG, team-game. *Variables with P < .05 and <FDR.
