ROC curve analysis: an example showing the relationships among serum lipid and
apolipoprotein concentrations in identifying patients with coronary artery disease
Not exact matches
In a genome - wide analysis of up to 17 503 participants in PROMIS, we identified genetic variants associated with either
apolipoprotein (a) isoform size or lipoprotein (a)
concentration.
We used a genetic approach to distinguish the relevance of two distinct components of this pathway,
apolipoprotein (a) isoform size and circulating lipoprotein (a)
concentration, to coronary heart disease.
Methods: In this mendelian randomisation study, we measured lipoprotein (a)
concentration and determined
apolipoprotein (a) isoform size with a genetic method (kringle IV type 2 [KIV2] repeats in the LPA gene) and a serum - based electrophoretic assay in patients and controls (frequency matched for age and sex) from the Pakistan Risk of Myocardial Infarction Study (PROMIS).
Finally, we compared phenotypic versus genotypic ORs to estimate whether
apolipoprotein (a) isoform size, lipoprotein (a)
concentration, or both were causally associated with coronary heart disease.
Specifically, the researchers looked at mutations in the
apolipoprotein A5 gene, a known determinant of triglyceride
concentrations.
Alfalfa seeds lower low density lipoprotein cholesterol and
apolipoprotein B
concentrations in patients with type II hyperlipoproteinemia.
Consumption of fructose - sweetened beverages for 10 weeks increases postprandial triacylglycerol and
apolipoprotein - B
concentrations in overweight and obese women.
