Moreover, we report positive associations between serum isoUDCA and the hepatic steatosis index (HSI), a calculated measure predictive of hepatic steatosis25 (β [95% CI] = 0.34 [0.11, 0.57], p = 3.54 × 10−3), and the liver function enzymes alanine aminotransferase (ALT) (β [95% CI] = 1.36 [0.2, 2.51], p = 2.16 × 10−2) and γ-glutamyl transferase (GGT) (β [95% CI] = 2.74 [0.77, 4.72], p = 6.84 × 10−3). Here, GPT is linked to Hepatic steatosis.
