[Retracted] Establishment of Difficult Caudal Epidural Blockade Prediction Model

<div>ROC curves based on the DCEB scoring model and its respective AUROC (95% CIs). The blue solid curve is the ROC curve from the development cohort (<i>n</i> = 202), while the dotted curve represents the validation cohort (<i>n</i> = 87). The ROC curve was used to evaluate the efficiency of prediction and an area under the ROC curve (AUROC) &gt; 0.75 is considered to indicate a good predictive ability.</div>
