Abstract excerpt
The triglyceride-glucose (TyG) index is a reliable composite marker of insulin resistance, which holds important clinical significance. Existing studies have predominantly focused on identifying TyG index-related genetic loci and single-nucleotide polymorphism (SNP)-based polygenic risk scores, however, the overall contribution of genetic factors to TyG index variation at the population level is still unclear. To...
