The primary outcome was overall mortality after LT, while several secondary outcomes including liver graft survival and rejection, the need for transfusions, the length of the intensive care unit (ICU) and hospital stay, and surgical complications were evaluated.

All studies included were cohort studies of good\/high quality on the Newcastle\u2010Ottawa scale (NOS), while in our analysis no publication bias was found, although there was substantial heterogeneity between the studies. Muscle mass was assessed using skeletal muscle index (SMI) in 14 studies, psoas muscle area (PMA) in seven studies, and psoas muscle index (PMI) in four studies. The prevalence of pre\u2010LT sarcopenia ranged from 14.7% to 88.3%. Pre\u2010LT sarcopenia was significantly associated with post\u2010LT mortality (Relative Risk [RR] = 1.84, 95% CI:1.41,2.39), as well as with a high risk of infections post\u2010LT, surgical complications, fresh frozen plasma (FFP) transfusions, and ICU length of stay (LOS).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Pre\u2010LT sarcopenia in patients with cirrhosis is a strong risk factor for clinically meaningful adverse outcomes after LT.
