aAE Athlete-exposure, with one athlete participating in one practice or one competition contributing one AE. AEs may be lower in SISS because participating teams practiced only 3 times per week
bAll RRs calculated with the lower of the two rates as referent group – the group with the significantly higher rate is bolded; CI denotes Confidence Interval. Bolded CIs indicate significance at alpha = 0.05
cRecurrent injuries for HS RIO included recurrence (this academic year) (3.0%), recurrence (previous academic year) (7.1%), other (0.2%) and missing (0.2%). Recurrent injuries for SISS included recurrent injury from this season (10.6%), recurrent injury from previous season (10.1%), complication of previous injury (2.2%), recurrence of an injury from another sport (5.7%), recurrence of a non-sport injury (4.8%), complication of a previous injury from another sport (0.4%) and missing (2.6%)
