We assessed sarcopenia defined according to the revised European Working Group on Sarcopenia in Older People (EWGSOP2) criteria, its baseline correlates, and its association with 24-month all-cause mortality. Materials and Methods: In this single-center prospective cohort at a tertiary nephrology center, 176 patients enrolled in December 2022 were followed for 24 months. Confirmed sarcopenia required both low handgrip strength and a low appendicular skeletal muscle index assessed by bioelectrical impedance. Physical performance was not assessed. Because the proportional-hazards assumption was not satisfied, restricted mean survival time (RMST) was used as the primary measure of the survival difference. Results: Sarcopenia was present in 46 of 176 participants (26.1%, 95% CI 20.2\u201333.1). Older age, lower serum albumin and phosphorus concentrations, lower Kt\/V, and longer time on maintenance hemodialysis were independently associated with sarcopenia. Thirty-one participants died during follow-up, and survival was lower among those with sarcopenia (log-rank p = 0.035). The adjusted RMST difference was \u22123.88 months (95% CI \u22126.49 to \u22121.28; p = 0.003). A Cox sensitivity analysis yielded a hazard ratio of 2.62 (95% CI 1.06\u20136.45). There was no evidence of a sarcopenia-by-sex interaction in the adjusted RMST analysis (p = 0.964). Conclusions: Confirmed sarcopenia was present in approximately one quarter of patients and was associated with approximately four months shorter restricted mean survival over 24 months. EWGSOP2-based assessment may provide prognostic information in this setting; whether routine screening or management based on sarcopenia status improves clinical outcomes remains to be determined.<\/jats:p>","DOI":"10.3390\/medicina62091735","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T08:05:43Z","timestamp":1788941143000},"page":"1735","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Sarcopenia
