Analyzing seven articles, a pooled HR of 1.91 (95% CI 1.09\u20133.34) for OS was reached, indicating that sarcopenic patients have a 91% higher risk of mortality compared to non-sarcopenic patients (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). There is no evidence of selective publication (<jats:italic>p<\/jats:italic>\u2009=\u20090.137).
