Fig. 4From: Establishment and validation of serum lipid-based nomogram for predicting the risk of prostate cancerCalibration curves of the predictive prostate cancer risk nomogram. The y-axis represents actual diagnosed cases of prostate cancer, the x-axis represents the predicted risk of prostate cancer. The diagonal dotted line represents a perfect prediction by an ideal model, and the solid line represents the performance of the training set (A) and validation set (B), with the results indicating that a closer fit to the diagonal dotted line represents a better predictionBack to article page
