Weak grip, weak anastomosis? Handgrip strength and sarcopenia as predictors of anastomotic leakage after colorectal cancer surgery

Figure 1 Axial computed tomography image at the third lumbar vertebra level showing the segmented skeletal muscle area (outlined in green). Skeletal muscle index was calculated as the cross-sectional area of the psoas, paraspinal, and abdominal wall muscles at the third lumbar vertebra level, normalized for height squared (cm²/m²).
