Combined associations of triglyceride-glucose index and biochemical sarcopenia index with cardiometabolic multimorbidity in middle-aged and older Chinese adults.
BACKGROUND Cardiometabolic multimorbidity confers a substantial disease burden in middle-aged and older adults. The triglyceride-glucose index is a reliable marker of insulin resistance, while the biochemical sarcopenia index reflects skeletal muscle mass. However, their combined association with cardiometabolic multim...
