Association between cumulative lipid indices and risk of cardiometabolic multimorbidity: findings from two independent longitudinal population cohorts
Cardiometabolic multimorbidity (CMM) is a major public health burden, with lipid metabolism disorders closely linked to its onset. Existing studies focus mostly on single lipid indicators, leaving the predictive value of cumulative composite lipid indices under-explored. We enrolled 4,782 CHARLS and 2,074...
