UCA1 and Familial prostate cancer: Similarly, to discriminate CAPRA high‐risk from low‐ and intermediate‐risk prostate cancer patients, the AUC of the UCA1 score of 0.705 (95% CI, 0.609–0.800) was a bit better than that of serum PSA alone (AUC 0.671, 95% CI, 0.572–0.771) or the urine UCA1 test alone (AUC 0.672, 95% CI, 0.574–0.771) (Figure 2E).
