From: Nomogram for overall survival of Japanese patients with bone-metastatic prostate cancer
External calibration of nomogram for 3-year survival. The predicted survival rate from the nomogram was well correlated with the actual observation. The blue line indicates the ideal reference line where the predicted probabilities match the observed proportions. The dashes represent the nomogram-predicted probabilities grouped for each of the three tertile groups, along with the respective confidence intervals.
