Receiver operating characteristic (ROC) curve for predicting low lean mass in cognitive impaired elderly. The ROC curves of BMI, GCA, L3SMI, MSMI, model 1 (combination of BMI, GCA, and L3SMI), and model 2 (combination of BMI, GCA, and MSMI) for predicting low lean mass. A The AUC of model 1 and model 2 was significantly greater than L3SMI. B There was no significant difference between BMI, GCA, L3SMI, and MSMI in the AUC. (Table 3) (See Supplemental Table 1, Additional file 2). Abbreviations: BMI, Body mass index; GCA, Global cortical atrophy; L3SMI, L3 skeletal muscle index; MSMI, Masseter skeletal muscle index
