Kaplan–Meier curves of overall survival (OS) of patients according to weight change before or during chemotherapy.

<p>A. OS curve of patients grouped by weight change trends during chemotherapy (<i>P</i> = 0.003). B. OS curve of patients grouped by weight loss during chemotherapy (<i>P</i> = 0.000). C. OS curve of patients with >5% weight loss before chemotherapy grouped by weight loss during chemotherapy (<i>P</i> = 0.004). D. OS curve of patients with ≤5% weight loss before chemotherapy grouped by weight loss during chemotherapy (<i>P</i> = 0.001).
