Serum TLR 9 and Resolvin E1 levels were statistically significantly higher in the sarcopenia group compared to the non-sarcopenia group (p < 0.001, p = 0.040), while TLR4 levels were higher in the sarcopenia group, but this increase was not statistically significant (p = 0.742) (Table 2, Supplementary Fig. 1). This evidence concerns the gene TLR4 and sarcopenia.
