- Time period: 8.5-year follow-up
-Population/Sample: 4679 Multi-Ethnic Study of Atherosclerosis (MESA) participants
- Comparator: Standard lipid panel to evaluate the risk of CHD.
- Study bias: None / -Description: Compared the standard lipid panel with nonstandard measurements ApoB and the ratio of ApoB/ApoA-I as well as NMR spectroscopy-derived measures of total LDL-P and the ratio of LDL-P to HDL-particles (HDLP) for evaluating CHD risk. We then determined whether these lipoprotein measures may impart risk independent of cholesterol measures.

- AssociatedCost: Not provided / - Description: Used the AHA/ACC risk calculator score as a baseline prediction model and determined whether
individual additions of ApoB, ApoB/ApoA-I, LDL-P, or
LDL-P/HDL-P improved CHD risk prediction.
Recording Method:
Cox proportional hazards analyses were conducted, and adjustments were made for sex, hypertension medication, systolic blood pressure, age, diabetes mellitus, smoking, and race/ethnicity, with individual adjustmentsfor LDL-C, non-HDL-C, or TC/HDL-C, followed by a combination of TC, LDL-C, HDL-C, and triglycerides. / - Number of Participants/ CVD events: 4679/ 233

Risk of Incident CHD for Lipoprotein Apo-B Markers Adjusted for Non-lipid Variables (sex, HT meds, systolic BP, age, DM, smoking, and race/ethnicity)+Specified Lipid Measures (TC+LDL-C+HDL-C+TGs)
