Psoas muscle area (PMA), a surrogate for total muscle mass, has been proposed as a useful survival prognosticator. However, few studies have validated the predictive value of decreased PMA in an Asian cohort or its predictive value after controlling for existing preoperative scoring systems (PSSs). In this study, we aim to answer: (1) Is PMA associated with survival in Han Chinese patients with spinal metastasis? (2) Is PMA a good prognosticator according to concordance index (c-index) and decision curve analysis (DCA) after controlling for six existing and commonly used PSSs?enMarginal effect; Psoas muscle; Sarcopenia; Spine metastases; Survival; Taiwanese[SDGs]SDG3journal article10.1016/j.clnu.2022.01.011351244692-s2.0-85123885018WOS:000767352400005https://scholars.lib.ntu.edu.tw/handle/123456789/594306
