;; significant partial correlation coefficients (covariates: age, sex, smoking, hypertension, and BMI) are highlighted in italics. HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol; VLDL: very low-density lipoprotein cholesterol; IDL-C: intermediate-density lipoprotein cholesterol. Lactonase was measured in 152/202 controls; Lp-PLA2 was measured in 111/202 controls.
