For 3-year mortality, sarcopenia remained a significant factor in the univariate analysis (HR: 0.541, 95% CI: 0.317–0.925, p = 0.025), along with CKI (HR: 4.224, 95% CI: 1.510–11.818, p = 0.006) and the use of diuretics (HR: 3.133, 95% CI: 1.189–8.253, p = 0.021). Here, CHKA is linked to sarcopenia.
