Triglyceride-glucose waist-to-height ratio in relation to prevalent and incident multimorbidity: cross-sectional and prospective evidence from four national studies
The triglyceride-glucose waist-to-height ratio (TyG-WHtR) integrates insulin resistance and central adiposity, but its association with generalized multimorbidity across populations and its dose–response threshold remain uncertain. We analyzed adults aged ≥ 50 years from five analytic samples derived from four national...
