Univariate associations between molecular markers and advanced prostate cancer at the time of diagnosis. Advanced cancer was defined as skeletal metastases or clinical stage ≥ T3. Predictive accuracy of each marker is given as AUC. To facilitate comparisons between markers, the odds ratios are for an increase of one-quarter of a standard deviation.
