Prognostic value of preoperative weight loss-adjusted body mass index on survival after esophagectomy for esophageal squamous cell carcinoma

Figure 1 Trends of poor survival were observed for patients with increasing preoperative weight loss and decreasing body mass index. A, B: Risk of reduced survival (blue line) increases with decreasing BMI (A) and increasing PWL (B). Median OS (golden line) decreases with decreasing BMI (A) and increasing PWL (B). PWL: Preoperative weight loss; BMI: Body mass index.

Figure 2 The threshold of BMI with 20. 0 kg/m² had the maximum χ² score, and was therefore the best cut-off point (A). The threshold of PWL with 8.8% had the maximum χ² score, and was therefore the best cut-off point (B). ws: weight stable; PWL: Preoperative weight loss; BMI: Body mass index.

Figure 3 Patients in the three groups were associated with significantly different overall survival (blue line: Group 1; green line: Group 2; golden line: Group 3).
