Values in second column are reported as mean ± SD or frequency (% of respondents).

Values in last column are reported as odds ratio (95% confidence interval) of injured vs. not injured. Values less than 1 indicate that, relative to the reference category, the odds of injury decreased.

– indicates the exposure variable was not estimable due to very low numbers in one of the injured categories.

Bolded variables were considered for entry into the final multivariable analysis because their univariate association was p < 0.10.
