Core Tip

Core Tip: The prevalence and effect of sarcopenia on patients undergoing liver transplantation (LT) remains to be determined partly because of different diagnostic criteria. Twenty-five studies involving 7760 patients undergoing LT were included in this meta-analysis. The pooled prevalence of sarcopenia in patients undergoing LT was 40.7%. Sarcopenia was associated with an increased risk of post-LT mortality in patients undergoing LT.
