Additional file 3: Supplementary Fig. 3. Prognostic impact of serum albumin and body mass index (BMI) in patients with rectal cancer. (a) Kaplan–Meier curve for overall survival (OS) in patients with rectal cancer according to the albumin level (n = 93). OS was not significantly different between high level albumin group (n = 50) and low level group (n = 43) (p = 0.29, log-rank test). (b) Kaplan–Meier curve for disease-free survival (DFS) in patients with rectal cancer according to the albumin level (n = 93). DFS was not significantly different between high level albumin group (n = 50) and low level group (n = 43) (p = 0.25, log-rank test). (c) Kaplan–Meier curve for overall survival (OS) in patients with rectal cancer according to the BMI (n = 93). OS was significantly higher in patients with a high BMI (n = 41) compared with those with a low BMI (n = 52) (p = 0.021, log-rank test). (d) Kaplan–Meier curve for disease-free survival (DFS) in patients with rectal cancer according to the BMI (n = 93). DFS was not significantly different between high BMI (n = 50) and low BMI (n = 43) (p = 0.10, log-rank test).
