INS and Insulin resistance: We incorporated the TyG index and TyG-BMI as the main surrogate markers of insulin resistance, and other four additional markers, including metabolic score for insulin resistance (MetS-IR), single-point insulin sensitivity estimator (SPISE), triglycerides to HDL-C ratio (TG/HDL-C), and TyG waist circumference-to-height ratio (TyG-WHtR).
