GPT and metabolic dysfunction-associated steatotic liver disease: A total of 1048 patients with NAFLD were included in this study and were divided into 4 groups based on the normalization of baseline ALT and/or GGT levels after follow-up: a both ALT and GGT abnormal group (n = 486), an ALT-only abnormal group (n = 281), a GGT-only abnormal group (n = 151), and a both ALT and GGT normal group (n = 130) (Fig. 1).
