Univariate and multivariate Cox-regression analysis.

<p>Results for univariate and multivariate Cox regression models. For every variable, the estimated hazard ratio HR and its corresponding 95% confidence interval are given, as well as the p-value when testing HR = 1. P-values below 0.05 are marked with a star (*). The categorical variable WHO grade is treated as factor variable, thus HR refers to the comparison of WHO grade II and WHO grade III, respectively, to WHO grade I.
