Fig. 4From: Risk factor analysis and a new prediction model of venous thromboembolism after pancreaticoduodenectomyCalibration curves of the VTE prediction nomogram. The x-axis represents the predicted medication nonadherence risk. The y-axis represents the actual diagnosed nonadherence. The diagonal dotted line represents a perfect prediction by an ideal model. The solid line represents the performance of the nomogram, and a closer fit to the diagonal dotted line represents a better predictionBack to article page
