Fig. 3From: Effects of endplate coverage and intervertebral height change on heterotopic ossification following cervical disc replacementROC curve of prosthesis-endplate depth ratio (A), intervertebral height change (B), and CP (C) for the prediction of posterior heterotopic ossification. The AUC are 0.728, 0.712, and 0.793, respectively. ROC curve, receiver operating characteristic curve; CP, combined parameter; AUC, area under the curveBack to article page
