Wang et al reported a sarcopenia score for evaluating patients. The authors are from multiple institutions in China.
Parameters:
(1) visceral to subcutaneous adipose tissue area ratio (VSR), example values 0.4 to 7 (square cm)/(square meter)
(2) intramuscular adipose tissue content (IMAC), example values -0.51 and -0.56
(3) age in years
(4) psoas muscle mass index (PMI), example values 4.18 and 7.04 (square cm)/(square meter)
(5) skeletal muscle mass index (SMI), example values 27 to 45 (square cm)/(square meter)

= SUM(points for all of the parameters) + 2.091
Interpretation:
• The sarcopenia score ranged from 0 to -5.
• It correlated with prognostic nutritional index (PNI) and postoperative complications.
