We used the Thyroid Feedback Quantile-based Index (TFQI), the TSH index (TSHI), and the Thyrotroph T4 Resistance Index (TT4RI) to represent thyroid hormones sensitivity and used Triglyceride-Glucose (TyG) Index, the Atherogenic Index of Plasma (AIP), and The Metabolic Score for Insulin Resistance (METS-IR) to represent IR. Here, TG is linked to Insulin resistance.
