Fig. 8From: Development of a nomogram model for prediction of new adjacent vertebral compression fractures after vertebroplastyCalibration curves of the training cohort model (A) and validation cohort model (B), the X-axis represents the predicted risk of refracture and the Y-axis represents the actual diagnosed patients with refracture. The diagonal dotted line represents a perfect prediction by an ideal model. The solid line represents the performance of the nomogram, of which a closer fit to the diagonal dotted line represents a better predictionBack to article page
