Also, there was no trend in the mean severity (slope = −0.22 days/year, R 2 = 0.03, p = 0.825) but a decreasing trend in the median severity (slope = −0.38 days/year, R 2 =1.00, p <0.001) of training injuries sustained by backs over the period 2007 to 2019.
There was no trend in the severity of match injuries over the four RWCs for backs (mean severity: slope = 1.1 days/year, R 2 = 0.70, p = 0.162; median severity: slope = 0.00 days/year, R 2 <0.01, p = 1.000) but an increasing trend for forwards (mean severity: slope = 1.4 days/year, R 2 = 0.91, p = 0.049; median severity: slope = 0.25 days/year, R 2 = 0.83, p = 0.087).
