Receiver operating characteristic curve analysis of CBMM, SARC-F score and sarcopenia. (A) Association between low GS with CBMM or SARC-F in males. (B) Association between low SMI with CBMM or SARC-F in males. (C) Association between sarcopenia with CBMM or SARC-F in males. The mSARC-F score was calculated as follows: mSARC-F = SARC-F + CBMM (sarcopenia, 4 points; not sarcopenia, 0 points) + sex (female, 2 points; male, 0 points) + age (≥65 years, 1 point; <65 years, 0 points). (D) Association between sarcopenia and mSARC-F in males. (E) Association between low GS with CBMM or SARC-F in females. (F) Association between low SMI with CBMM or SARC-F in females. (G) Association between sarcopenia with CBMM or SARC-F in females. (H) Association between sarcopenia and mSARC-F in females. (I and J) Association between low GS and mSARC-F in males and females, respectively. (K and L) Association between low SMI and mSARC-F in males and females, respectively. The x-axis is the sensitivity and the y-axis is the specificity; P-values represent comparisons between the AUCs of CBMM and SARC-F in each panel. The fine line refers to CBMM and the bold line refers to SARC-F. AUC, area under the curve; CBMM, calculated body muscle mass; GS, grip strength; skeletal muscle index.
