Results from the analyses showing the seasonal percentages of change in injury incidence, injury severity, injury burden, reinjury incidence, injury absence and match availability/training attendance between the 2001/2002 and the 2018/2019 season. Results are expressed as the seasonal change, with 95% CIs*

Negative values represent a reduction. Positive values represent an increase.
*The dependent variables injury severity and availability were log transformed. Tests for normality (Kolmogorov-Smirnov and Shapiro-Wilk) showed that this transformation was appropriate for the dependent variables.
