For the models of E-DII and inflammatory mediators (Table 4), AUC measurements for E-DII + cfDNA (AUC = 0.805) were considered a good discrimination, and the evaluation was as acceptable for cytokines IL-1β, IL-6, TNFα and CRP (0.7 < AUC < 0.8) i.e., it enabled sarcopenia diagnosis64. The gene discussed is CRP; the disease is sarcopenia.
