Whether thyroid\u2010related hormones within the euthyroid range can help identify sarcopenia risk remains unclear.

Sarcopenia was defined per Asian Working Group for Sarcopenia 2019 criteria. Muscle mass was assessed via multifrequency bioelectrical impedance analysis, handgrip strength via dynamometer, and gait speed via 6\u2010m walk test. Multivariate linear and logistic models were adjusted for demographics, diabetes duration, body mass index, nephropathy, glycated hemoglobin, and antidiabetic medications. Discriminatory ability was evaluated using receiver operating characteristic curves, change in the area under the receiver operating characteristic curve (\n                      <jats:italic>\u0394<\/jats:italic>\n                      AUROC), and net reclassification indices (net reclassification improvement [NRI]; bootstrapped).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Higher free triiodothyronine (FT3) levels correlated with greater muscle mass, handgrip strength, and gait speed. Among thyroid markers, FT3 showed the strongest discrimination for sarcopenia (AUROC = 0.633). The optimal cutoff was 3.62\u2009pmol\/L (sensitivity, 85.6% and specificity, 35.7%), although overall performance was modest. Low FT3 independently predicted sarcopenia (odds ratio [OR], 2.26;\n                      <jats:italic>p<\/jats:italic>\n                      = 0.002). The association remained significant in females (OR, 3.29) but not in males (OR, 1.83); no sex interaction was detected.
