Note: The p -values within the parenthesis are factor with independent predictive significance using the univariate t -test or analysis of variance. The p -values in bold are significant according to the multivariate general linear model and excluded from the model. The p -values in italic are nonsignificant and not included in the model after univariate analysis. In all significant parameters, the presence of the fracture pattern was associated with a worse outcome. Regarding age group, the worse outcome was in the elderly group.
