Reduced uremic metabolites are prominent feature of sarcopenia, distinct from antioxidative markers for frailty

Heatmap analysis and PCA for sarcopenia. (A) Heatmap analysis of metabolites involved in sarcopenia (top panel), and SMI (bottom). The heat map shows Z-scores of peak areas from LC-MS analysis. (B) PCA plot of 19 elderly participants. 22 sarcopenia markers were analyzed.
