Multivariate analysis for demographic variables in table, and cumulative trauma event categories. Only statistically significant demographic variables (P < 0.05) following univariate analysis included in multivariate analysis.

Only statistically significant (P < 0.05) adjusted odds ratios from multivariate analysis presented.
