HR, hazard ratio (describes the relative risk of the event at any given time based on comparing the group with the reference group); 95% CI, 95% confidence interval (A 95% confidence interval means that 95% of the values of an unobservable parameter of interest would set in the interval if the experiment is repeated); na, not available; ref, reference
* Significant p-value
a Pathological T category refers to the stage of primary tumor in the TNM tumor staging system. pT2 = Tumor confined within prostate, pT3 = Tumor invading extraprostatic tissue and/or seminal vesicle(s).
