However, when taking only patients with NASH into consideration, our results showed lower levels of ALT, AST, and GGT at follow-up in the SG group compared to RYGB, with a p value of 0.029, 0.06, and 0.04, respectively, and lower levels of LDL and cholesterol in the RYGB (p value 0.002 and p value 0.01, respectively) compared to SG at follow-up. The gene discussed is GPT; the disease is metabolic dysfunction-associated steatohepatitis.
