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 tumor (pT) category refers to the stage (i.e. size and extent) of primary tumor in the TNM tumor staging system. pT2 = Tumor confined within prostate, pT3 = Tumor invading extraprostatic tissue and/or seminal vesicle(s).
b N category describes in TNM system weather (N1) or not (N0) the cancer has spread to the regional lymph nodes.
