Compared with conventional treatments, combined treatment could clearly improve the liver function of NAFLD patients, which could reduce the levels of ALT (MD = −7.69 U/L, 95% CI: −11.88 to −3.51, p < 0.001), AST (MD = −9.58 U/L, 95% CI: −12.84 to −6.33, p < 0.01), and it also had a certain impact on regulating lipid metabolism, which could reduce the levels of TC (MD = −0.85 mmol/L, 95% CI: −1.22 to 0.48, p < 0.01), TG (MD = −0.45 mmol/L, 95% CI: −0.64 to 0.21, p < 0.01). This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
