Models for age-specific estimation of appendicular skeletal muscle mass using the ultrasound-measured rectus femoris muscle thickness
Figure 2. Bland-Altman plots for estimated ASM and BIA-measured ASM across groups and models. The solid and dashed lines represent the mean difference and 95% LOA, respectively. (A) Group-specific model derived from Group A applied to Group A, (B) group-specific model derived from Group B applied to Group B, (C) group-specific model derived Group C applied to Group C, (D) total group model applied to Group A, (E) total group model applied to Group B, (F) total group model applied to Group C. Abbreviations: BIA: bioelectrical impedance analysis; ASM: appendicular skeletal muscle mass; 95% LOA: 95% limit of agreement.
