Comprehensive abdominal composition evaluation of rectal cancer patients with anastomotic leakage compared with body mass index-matched controls

Figure 1  Flow chart of patient inclusion and exclusion.

Figure 2 Radar plot for comparison of abdominal composition related parameters between the anastomotic leakage group and the control group. AC: Abdominal circumference; SFA: Subcutaneous fat area; SFT: Subcutaneous fat thickness; SMA: Skeletal muscle area; SMI: Skeletal muscle index (SMA/height²); VFA: Visceral fat area; APD: Anterior to posterior diameter of abdominal cavity; TD: Transverse diameter of abdominal cavity; AL: Anastomotic leakage.

Figure 3 Importance of each feature in the development of anastomotic leakage. AC: Abdominal circumference; SFA: Subcutaneous fat area; SFT: Subcutaneous fat thickness; SMA: Skeletal muscle area; SMI: Skeletal muscle index (SMA/height²); VFA: Visceral fat area; APD: Anterior to posterior diameter of abdominal cavity; TD: Transverse diameter of abdominal cavity; AL: Anastomotic leakage.
