As shown in Figure 2, participants with NAFLD exhibited higher mtDNAcn (6.70 ± 0.48 vs. 6.55 ± 0.59, P = 0.033), 8-oxo-dG (3.62 ± 0.68 vs. 3.40 ± 0.84 pg/mL, P = 0.013), and IL-6 (1.31 ± 0.60 vs. 1.16 ± 0.60 pg/mL, P = 0.031) than those without NAFLD, whereas we failed to observe a statistical difference in SOD (P = 0.786), GR (P = 0.891), or TNF-α (P = 0.758) between the two groups. This evidence concerns the gene SOD1 and metabolic dysfunction-associated steatotic liver disease.
