QMCSA values in the normal and lower SMI groups and in the non-sarcopenia and sarcopenia groups. (a) QMCSA value in either normal or lower SMI group divided by sex. (b) ROC curve of QMCSA as a predictor of lower SMI. (c) QMCSA value in either non-sarcopenia or sarcopenia group divided by sex. (d) ROC curve of QMCSA as a predictor of sarcopenia. ROC receiver operating characteristic.
