The diagnostic values of serum miR-34a (AUC = 0.781; 95% CI = 0.663–0.899; P = 0.001) and miR-122 (AUC = 0.858; 95% CI = 0.769–0.947; P = 0.001) are comparable to serum ALT (AUC = 0.832; 95% CI = 0.729–0.935; P = 0.001) in discriminating NAFLD patients with healthy controls (Table 3 and Fig 5). Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
