Fig. 1From: Low LPA gene kringle IV-2 repeat copy number association with elevated lipoprotein (a) concentration as an independent risk factor of coronary atherosclerotic heart disease in the Chinese Han populationa Shows an XY scatter plot of Lp(a) mass and particle concentration, and the linear relationship with a regression equation: YLp(a)-mass = 6.565XLp(a)-particle, R2 = 0.852, P < 0.001. b Shows an XY scatter plot of KIV-2 copy number and Lp(a) mass concentration for all participants. The abscissa is KIV-2 copy number, and the left ordinate is Lp(a) mass concentration. c Shows KIV-2 copy number and Lp(a) particle concentration. The abscissa is KIV-2 copy number, and the left ordinate (right axis) is Lp(a) particle concentration. There is a negative correlation between Lp(a) level and KIV-2 copy number, i.e., the smaller the KIV-2 copy number the higher the Lp(a) concentrationBack to article page
