Abbreviations: AUC, area under the receiver operating curve; CI, confidence interval; wGRS weighted genetic risk score; wnGRS, weighted non-genetic risk score.
a AUCs and P values were estimated for ROC analyses
b Pdiff < 1×10−4, AUCs of the three risk score models, wGRS, wnGRS, and wGRS+wnGRS, were significantly different from each other at P < 0.0001.
c wGRS, the weighted genetic risk score model composed of the ten replicated SNPs.
d wGRS+wnGRS1, the combined model of wGRS model composed of 10 validated SNPs plus wnGRS1 comprised of age, sex, BMI.
e wnGRS2 was comprised of wnGRS1 plus cigarette smoking, and alcohol consumption.
f wnGRS3 was comprised of wnGRS1 plus cigarette smoking, SBP and Hb.
g wnGRS4 was comprised of wnGRS3 plus alcohol consumption, DBP, and BUN.
