"SMD"=skeletal muscle radiodensity (HU); HR=hazard ratio

SMD and Sarcopenia model adjusted for visceral and subcutaneous adipose tissue in quartiles

Models additionally adjusted for age at diagnosis (continuous), sex (ref=Male), race (ref=White), site (ref=Proximal), stage (ref=I), grade (ref=well), chemotherapy (ref=No), radiation (ref=No), smoking history (ref=Never), comorbidity score (ref=0) and partitioned BMI (continuous)
