Table 2 Results of multivariable Cox regression analysis with hazard ratios for each variable for time to BCR and time to skeletal metastasis, with PSA as a continuous variable and Gleason score, local tumour stage and PET/CT findings dichotomized

From: Pre-treatment 18F-choline PET/CT is prognostic for biochemical recurrence, development of bone metastasis, and cancer specific mortality following radical local therapy of high-risk prostate cancer
