On the other hand, Naive DN (CD4-CD8-) AC (OR = 0.983, 95% CI 0.974–0.992, P = 1.05e − 02), CD14- CD16- AC (OR = 0.985, 95% CI 0.976–0.993, P = 1.05e − 02), and CD62L- CD86 + myeloid DC AC (OR = 0.982, 95% CI 0.972–0.992, P = 1.05e − 02) showed a significant negative causal effect on AAA risk. Here, SELL is linked to triple-A syndrome.
