Fig. 1From: Hypomethylation of ABCG1 in peripheral blood as a potential marker for the detection of coronary heart diseaseMethylation difference of ABCG1 between ICM cases (A), non-ICM CHD cases (B) and controls in the prospective nested case–control study. The point plots showed the methylation differences of CpG sites in the ABCG1 amplicon. The squares indicated the hypomethylation in cases vs. controls, and the triangles indicated the hypermethylation in cases vs. controls. The p values were calculated by logistic regression adjusted for age, gender, smoking, alcohol consumption, hypertension, diabetes, TC, TG, HDL-C, LDL-C, and batch effect. The solid lines indicated the threshold of p value = 0.05Back to article page
