Combined low muscle mass and body mass index for prognosis in esophageal squamous cell carcinoma patients receiving immunochemoradiotherapy

Figure 2 Low muscle mass and associated factors in esophageal cancer patients. A-C: Present violin plots of body mass index (BMI) distribution across different clinical subgroups; D: A forest plot of multivariable logistic regression analysis for factors associated with low muscle mass (LMM); E: Depicts the nonlinear association between BMI and LMM using restricted cubic spline analysis; F and G: Display the receiver operating characteristic curve and calibration curve of the LMM prediction model, respectively. OR: Odds ratio; CI: Confidence interval; BMI: Body mass index; TNM: Tumor-node-metastasis; AUC: Area under the curve; FPR: False-positive rate; TPR: True-positive rate.
