Associations of Triglyceride-Glucose Composite Indices with Mortality in Adults with T2DM

1,940 adults with type 2 diabetes were followed to assess mortality risk using triglyceride-glucose composite indices. TyG-WHtR showed the strongest association with all-cause mortality, with a hazard ratio of 1.44. The dataset, authored by Honglin Liu and last updated in May 2026, contains results from Cox regression and time-dependent ROC analyses.

Use Cases

• Evaluating the prognostic value of TyG-WC, TyG-WHR, TyG-WHtR, TyG-ABSI, and TyG-WWI indices for mortality based on the study results.
• Conducting subgroup analyses stratified by age, sex, smoking, drinking, and hypertension status as described in the methodology.
• Exploring nonlinear relationships between composite metabolic indices and mortality using restricted cubic spline models.
• Assessing the predictive performance of different TyG-related indices via time-dependent AUC calculations.

Strengths

• Results are based on a cohort of 1,940 adults with T2DM aged 45 years and older.
• The analysis includes hazard ratios for five distinct composite indices (TyG-WC, TyG-WHR, TyG-WHtR, TyG-ABSI, TyG-WWI) with specific confidence intervals.
• Study includes subgroup analyses and nonlinear relationship exploration via restricted cubic splines.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 30.4 KB, indicating limited scope, likely containing summary results rather than raw patient-level data.
