^aP < 0.0083, vs non-metabolic dysfunction-associated steatotic liver disease (MASLD) group.

^bP < 0.0083 vs mild MASLD group.

^cP < 0.0083 vs moderate MASLD. P values for differences between four groups were obtained by one-way analysis of variance (Bonferroni correction).

NMASLD: Non-metabolic dysfunction-associated steatotic liver disease; Mi-MASLD: Mild metabolic dysfunction-associated steatotic liver disease; Mo-MASLD: Moderate metabolic dysfunction-associated steatotic liver disease; S-MASLD: Severe metabolic dysfunction-associated steatotic liver disease.
