Body mass index predicts low muscle mass in esophageal squamous cell carcinoma patients undergoing chemoradiotherapy

Figure 2 Survival analysis by combined body mass index and muscle mass status. Patients were stratified by body mass index (BMI) (low: < 18.5 kg/m²; normal: 18.5-24 kg/m²; high: ≥ 24 kg/m²) and muscle mass status [normal muscle mass or low muscle mass (LMM)]. Panels A-E use high BMI and normal muscle mass as the reference group (blue curves). A: High BMI and LMM; B: Low BMI and normal muscle mass; C: Low BMI and LMM; D: Normal BMI and normal muscle mass; E: Normal BMI and LMM; F: Uses normal BMI and normal muscle mass as the reference group (blue curve). BMI: Body mass index.
