Figure 4.
The prognostic value of BMI-muscle metabolism index (BMM Index). Patients who died or underwent tracheostomy within 24 months from onset are presented as red circles, and the remaining patients are presented as black circles (a). The shaded area shows the body mass index-muscle metabolism (BMM) index ≥ 1 (a). Time-dependent receiver operating characteristic curve analysis shows that the BMM index strongly predicts the incidence of endpoints within two years from the onset (area under the curve = 0.82) (b).
