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).
| Low Lean for Age | Normal Lean for Age | Total | |
|---|---|---|---|
| (ALMI Z ≤ -1.0 SD) | (ALMI Z > -1.0 SD) | ||

Low Fat-Adjusted ALMI for Age • (ALMIFMI Z ≤ -1.0 SD) |
1345 (9.1%) | 788 (5.3%) | 2133 (14.4%) |

Normal Fat-Adjusted ALMI for Age • (ALMIFMI Z > -1.0 SD) |
943 (6.4%) | 11774 (79.3%) | 12717 (85.6%) |
| Total | 2288 (15.4%) | 12562 (84.6%) | 14850 (100%) |
