Cox‐regression analysis for disease‐free survival. Liver steatosis and body composition variables were eliminated from the multivariable model by stepwise backward elimination if P > 0.05. Liver steatosis was defined as a steatosis grade of ≥1. Z‐scores are included as continuous variables. Radiation attenuation (RA) is the average Hounsfield unit value of a certain type of tissue; a low RA is associated with a high tissue triglyceride content. Decrease was defined as a Δ of < −2%/100 days. *P < 0.05. ASA, American Society of Anaesthesiologists; RA, radiation attenuation; SAT, subcutaneous adipose tissue.
