Development and validation of a nomogram for predicting postoperative venous thromboembolism risk in patients with hepatocellular carcinoma

Figure 1 Flow chart of the patients enrolled in the final study cohorts. VTE: Venous thromboembolism; TNM: Tumor-node-metastasis; DCA: Decision curve analysis; ROC: Receiver operating characteristic.

Figure 2 Multivariate logistic regression analysis of venous thromboembolism risk factors in the training cohort. KPS: Karnofsky Performance Scale; TNM: Tumor-node-metastasis; WBC: White blood cell count; Hb: Hemoglobin; FIB: Fibrinogen; OR: Odds ratio; CI: Confidence interval.
