S100A6 and triple-A syndrome: In addition, a binary logistic regression was conducted between AAA and non-AAA groups, which demonstrated that both high-level PRL and PRA were positively associated with AAA development with an unadjusted OR of 1.099 [(95% CI, 1.026–1.176), and p = 0.007] for the PRL and 1.070 [(95% CI, 1.013–1.129), and p = 0.014] for PRA, and adjusted OR of 1.100 [(1.028–1.176); p = 0.005] for PRL and 1.075 [(1.015–1.138); p = 0.014] for PRA in model 1 and 1.102 [(1.024–1.186); p = 0.009] for PRL and 1.088 [(1.019–1.162); p = 0.012] for PRA in model 2, respectively (Supplementary Table S4).
