Serum δ65Cu changes in non-alcoholic fatty liver disease (NAFLD). a Serum δ65Cu values for different stages of NAFLD. Statistical analysis was performed by Kruskal–Wallis and Dunn’s multiple comparisons test. b Receiver Operating Characteristic (ROC) analysis of serum δ65Cu values. P-values were two-sided and considered significant when lower than 0.05. F0–F4 refers to the corresponding fibrosis stage. Healthy males: n = 12, healthy females: n = 10. Non-alcoholic fatty liver (NAFL): n = 10. Non-alcoholic steatohepatitis (NASH) F0–F2: n = 10. NASH F4: n = 4
