The chi-square test and multivariable logistic regression analysis with adjustment for covariates revealed that the -219G-->T polymorphism of APOE, the -519A-->G of MMP1, the -866G-->A of UCP2, the -1607/1G-->2G of MMP1, the A-->G (Lys45Glu) of MMP3, the G-->A (Ala163Thr) of AGTR1, the G-->A (Gly670Arg) of PECAM1, and the -55C-->T of UCP3 were significantly (false discovery rate <0.05) associated with CKD.
The Chi-square test, multivariable logistic regression analysis with adjustment for covariates, as well as a stepwise forward selection procedure revealed that ten different polymorphisms were associated (P<0.05) with the prevalence of CKD in high- or low-risk subjects: the -519Aright curved arrow G polymorphism of MMP1, the 1061Aright curved arrow G (Ile405Val) polymorphism of CETP, the Aright curved arrow G (Lys45Glu) polymorphism of MMP3, the -219Gright curved arrow T polymorphism of APOE, the Aright curved arrow G (Ile1205Val) polymorphism of COL3A1, the -863Cright curved arrow A polymorphism of TNF, and the 1454Cright curved arrow G (Leu125Val) polymorphism of PECAM1 in high-risk subjects; and the 1167Cright curved arrow T (Asn389Asn) polymorphism of TGFBR2, the 2386Aright curved arrow G (Ile796Val) polymorphism of SCAP, and the TAAAright curved arrow del polymorphism of PDE4D in low-risk subjects.
