Body composition and resting energy expenditure in carriers vs. non-carriers. Boxplots show Lean Body Mass (upper left), Body Cell Mass (BCM; upper right), ratio between Extracellular Mass (ECM) and BCM (center left), Phase Angle (center right), measured Resting Metabolic Rate (mRMR; bottom left), and Metabolic Ratio (bottom right) in ALS mutation carriers (blue) and non-carriers (red). p-values based on Wilcoxon rank sum test.
