Fig. 3From: Overall survival in patients over 40 years old with surgically resected pancreatic carcinoma: a SEER-based nomogram analysisCalibration plots of nomogram for 1-, 2- and 3-year OS prediction of the training set (a, b, c) and validation set (d, e, f)X-axis represents the nomogram-predicted OS probability and Y-axis represents the actually observed OS probability. The diagonal line indicates the perfect nomogram reference. Dots with bars represent nomogram-predicted probabilities together with 95% confidence interval.Back to article page
