Calibration curves for 1-, 2-, 3-, and 5-year overall survival prediction in the primary training (the US) and validation cohorts (Belgium, the Netherlands, Slovenia, and Norway). Nomogram-predicted survival is plotted on the x axis and actual survival on the y axis. The vertical bars at the top represent the frequency of the predicted probability of survival. A plot along the 45-degree line indicates a perfect calibration model where the predicted probabilities are identical to the actual proportions
