Fig. 6: The correlation of blood PLA concentration and physical performance with human patients with sarcopenic phenotype.

a Non-sarcopenic (69.5 ± 5.89 years) or patients with sarcopnic phenotype (71.3 ± 6.62 years) blood samples were collected and D-PLA concentration in human blood samples was measured. Created in BioRender. Ryu, D. (2024) BioRender.com/s00v719. b Muscle mass and Skeletal muscle mass index of non-sarcopenic or sarcopenic participants. Muscle function of participants were evaluated with Grip strength (****p < 0.0001), Gait speed (****p < 0.0001), FTSS (****p < 0.0001), and SPPB score (****p < 0.0001).
