Receiver operating characteristic (ROC) curve analysis assessed the capacity for prediction of eGDR, relative to triglyceride\u2010glucose (TyG) index, Homeostasis Model Assessment of Insulin Resistance (HOMA\u2010IR), and glycated hemoglobin (HbA1c).

Multivariate logistic regression, adjusted for covariates, found that T3 had a significantly lower odds ratio for depressive symptoms than T1 (OR = 0.68, 95% CI: 0.48\u20130.97). RCS curves confirmed a linear trend (P for non\u2010linearity = 0.764). The negative association was particularly evident in participants under 60, non\u2010Hispanic Black individuals, those living alone, and those without cardiovascular disease. ROC analysis indicated that eGDR had better discriminative power for depressive symptoms than TyG, HOMA\u2010IR, and HbA1c (\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.05).
