Fig. 4From: Correlation between the Charlson comorbidity index and skeletal muscle mass/physical performance in hospitalized older people potentially suffering from sarcopeniaROC curve of low skeletal muscle mass and CCI. ROC curves were constructed to evaluate the sensitivity and 1-specificity of CCI in the diagnosis of low skeletal muscle mass.
