If articles used more than one statistical method to analyse workload and injury, they are included more than once in the table. We only report analyses used to analyse workload–injury associations, not other analyses reported in the articles (eg, ANOVA to test for differences in total workloads at separate times of the season).

*Clausen

*et al*39 also report fitting multilevel models, but do not report any of the results—presenting only their GEE findings in their results and discussion.†Relative risk here refers to the use of RR as a primary analysis based on risks in different categorical groups, not as an effect estimated from another model. For example, comparing risks among different load groups like Hulin

*et al*33 47 are counted here, whereas Gabbett and Ullah66 derived RR from their frailty model, and Clausen*et al*39 derived RR from their Poisson model, but neither are included in the count for RR.ANOVA, analysis of variance; GEE, generalised estimating equation.
