Predictors of one-year adverse outcomes after laparoscopic resection for hepatocellular carcinoma: Development and validation of an early-warning model

Figure 5 Receiver operating characteristic, decision curve analysis, and calibration curve validation of the least absolute shrinkage and selection operator model (validation group). A: The receiver operating characteristic curve demonstrates the model’s good discrimination ability in the validation group (area under the curve = 0.750); B: Decision curve analysis reveals the model’s significant clinical net benefit within the 0%-96% threshold range; C: The calibration curve shows a good fit and favorable calibration between model predictions and the actual occurrence rate. The χ² value of the goodness-of-fit test is 8.2821, and the P value is 0.4064. TPR: True positive rate; FPR: False positive rate; AUC: Area under the curve; CI: Confidence interval.
