Clinical value of predicting bleeding after endoscopic submucosal dissection for early esophageal cancer

Figure 1 Construction of a gradient boosting machine prediction model for bleeding after endoscopic submucosal dissection in patients with early esophageal cancer. A: Number of iterations and error rate; B: Relative importance ranking of variables in the gradient boosting machine model. CRP: C-reactive protein.

Figure 2 Comparison of the predictive effect of the gradient boosting machine model and bleeding after endoscopic submucosal dissection trend from Japan score on postoperative bleeding after endoscopic submucosal dissection in patients. A: Receiver operating characteristic (ROC) curve of the bleeding after endoscopic submucosal dissection (ESD) trend from Japan score for predicting bleeding after ESD in patients with early esophageal cancer; B: ROC curve of the gradient boosting machine prediction model for predicting bleeding after ESD in patients with early esophageal cancer. AUC: Area under the curve.
