Table 1.
Regressions of FMI on ALMI Z-Score within age, sex, and race categories.
Table 2.
Regression of FMI on ALMI Z-Scores within 20–40 year-olds.
Fig 1.
ALMI Z-Scores and T-Scores are strongly positively correlated with FMI Z-Scores and T-Scores.
The scatter plots and lowess curves illustreate a) the correlation between lean/adjusted lean and fat Z -score, with cutoff of -1 displayed as line. b) the correlation between lean/adjusted lean and fat-T-score with cutoff of -2 as line.
Table 3.
Assessment of the correlation between standard and fat-adjusted measures of low lean mass for age (as defined as an ALMI greater than 1 SD below the mean).
Table 4.
Assessment of the concordance between standard and fat-adjusted measures of sarcopenia (as defined as an ALMI greater than 2 SD below the mean for 20–40 year-olds).
Fig 2.
Reclassification of individuals from normal lean mass to low lean mass occurs among those with high FMI.
Fig 2a demonstrates a box plot of FMI (dark grey) and ALMI (light grey) Z-Scores among subjects who were reclassified with the fat-adjusted definitions of low lean. Fig 2b is a box plot of FMI (dark grey) and ALMI (light grey) T-Scores among subjects who were reclassified with the fat-adjusted definitions of sarcopenia.
Fig 3.
Younger individuals are likely to be reclassified as normal based on ALMIFMI, while elderly individuals are likely to be reclassified as having low lean mass.
Illustration of subjects that were reclassified with the fat-adjusted definition of sarcopenia across the age range demonstrating greater re-classification to sarcopenia among older individuals.
