Relationships between adiposity-adjusted lean mass and muscle density in RA and controls.
Low muscle density Z-Scores are observed among RA patients with low ALMIFMI (lean mass scores adjusted for adiposity). The relationship is significantly stronger in RA such that RA patients with low lean mass have the greatest deficits in muscle density compared to reference participants with similarly low lean mass.
Abbreviations: ALMIFMI= Adiposity-adjusted Appendicular Lean Mass Index
