The fat\u2010to\u2010muscle ratio (FMR) is a potential screening measure for sarcopenic obesity; however, its diagnostic accuracy compared with other tools has not been evaluated. This study compared the diagnostic performance of several screening tools for sarcopenic obesity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This cross\u2010sectional analysis used data from the National Center for Geriatrics and Gerontology Study of Geriatric Syndromes (NCGG\u2010SGS), a national cohort study conducted in Japan.
