Letter: Response to Comment on: "The Association Between Epicardial Adipose Tissue Thickness and the Triglyceride-Glucose Index in Prediabetic Obese Patients".

This article focuses on the authors’ response to critiques regarding their study on the association between epicardial adipose tissue (EAT) thickness and the triglyceride-glucose (TyG) index in prediabetic obese patients. They justify the use of echocardiography for EAT measurement due to its accessibility and cost-effectiveness despite acknowledging that computed tomography (CT) and magnetic resonance imaging (MRI) offer superior resolution. For assessing insulin resistance, the authors defend their use of the TyG index and homeostasis model assessment of insulin resistance (HOMA-IR) as practical surrogate markers instead of the hyperinsulinemic-euglycemic clamp, the gold standard method. They also discuss age-related findings and potential multicollinearity among metabolic predictors, emphasizing cautious interpretation of multivariate analyses due to sample size and methodological limitations.
