Moreover, in sarcopenia group, Hb and ALB were lower (80.8 ± 22 vs. 88.1 ± 25 g L−1, p = 0.007; 33.5 ± 12.5 vs. 36.6 ± 13.5 g L−1, p = 0.020), and both LE8 and LC9 scores were markedly reduced (LE8: 63.3 ± 12.3 vs. 67.6 ± 10.3, p = 0.001; LC9: 60.4 ± 11.6 vs. 68.4 ± 10.8, p < 0.001). Here, GSTM1 is linked to sarcopenia.
