ABCG1 and metabolic syndrome: The Kruskal–Wallis rank sum test showed that the methylation rate between obesity and nonobesity, hypertension and nonhypertension, and dyslipidemia and nondyslipidemia had statistical significance (p < 0.05), and logistic regression analysis found that the methylation level of the ABCG1 gene was statistically significant in relation to obesity, hypertension, and dyslipidemia (p < 0.05), but not in relation to hypertension (p > 0.05).
