GPT and obesity due to melanocortin 4 receptor deficiency: Figure 1 provides a detailed illustration of the varying distributions of fatty liver and pancreas among the four groups. Compared to the other groups, Group 4 exhibits a higher proportion of males. Group 1 has a lower BMI relative to the other groups. Furthermore, Groups 1 and 2 display lower levels of TG, FFA, ALT, and uric acid compared to Groups 3 and 4, indicating that the combination of fatty liver in people with obesity is associated with more pronounced metabolic abnormalities (Table 1).
