Multivariate logistic regression analysis of AAA risk factors revealed plasma PRDX6 concentration, hypertension, and smoking to be independent predictors of the presence of AAA [Odds Ratio CI (95%): 1.060 (1.006–1.117), p < 0.05 for PRDX6; 5.775 (1.670–19.973), p < 0.01 for hypertension; and 10.028 (1.139–88.311), p < 0.05 for smoking)]. The gene discussed is PRDX6; the disease is triple-A syndrome.
