ap values were calculated using the Cox-proportional hazard model, Primary tumor site , age and PS,gender.
bp values were calculated using the Cox-proportional hazard model, adjusted with age, Primary tumor site and PS.
cp values were calculated within sarcopenia group. dp values were calculated within nonsarcopenia group.
