GPT and hyperthyroidism: Indicators of liver function, such as ALT, AST and AKP, were higher in both the Init_GD and Treat_GD groups than in the HCs (p < 0.0001 among the three indicators), which is consistent with the changes reported in a previous study regarding hyperthyroidism-related liver injury (Li et al., 2015); the Treat_GD group showed more significant differences than the Init_GD group, although ALT and AST levels showed no significant differences between them (p = 0.858 and p = 0.687).
