Our results showed higher PRL was significantly associated with AAA development with an unadjusted OR of 1.456 [(95% CI, 1.180–1.797), and p < 0.001] compared with VV and 1.064 [(95% CI, 1.002–1.130), and p = 0.041] compared with PAD (Table 3). The gene discussed is PRL; the disease is peripheral arterial disease.
