Most notably, interleukin-6 (IL-6) was significantly higher in those diagnosed with sarcopenia [17,18,21] with Rong et al. [17] reporting serum levels of 43.80 ± 10.13 pg/mL (n = 82) compared to 27.38 ± 9.53 pg/mL in the control group (p < 0.05) and Bian et al. [18] reporting 49.77 ± 22.14 pg/mL serum IL-6 in 79 individuals vs. 39.72 ± 29.53 pg/mL in the control group (p = 0.03). Here, IL6 is linked to sarcopenia.
