GPT and Insulin resistance: Non-invasive indices for assessing liver damage in PCOS include the Fibrosis-4 (FIB-4) index [based on age, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and platelet count], the BAAT index [calculated from age, body mass index (BMI), ALT, and triglyceride levels], the homeostasis model assessment of insulin resistance (HOMA-IR), and androgen levels [14,15,16,17].
