No dependence of CCL20 local expression on age was observed in any of the groups, AAA or normal aorta (AAA: log10 CCL20 = −3.119 + 0.101 ∗ age −0.000758 ∗ age2, age coefficient p = 0.549, age2 coefficient p = 0.523, R = 0.099; Controls: Log10 CCL20 = −1.292 + 0.0297 ∗ age − 0.000326 ∗ age2, age coefficient p = 0.777, age2 coefficient p = 0.739, R = 0.124). The gene discussed is CCL20; the disease is triple-A syndrome.
