If at the initial screening for AAA we measure both the aorta diameter, R0, and the concentration of IL-6 in the blood, I60, then by simulating the model with these values of R(0) = R0 and I60 (in Eq (13)), we can predict the AAA diameter at any future time T. Figs 6 and 7 simulate the cases T = 300 and T = 500 days. This evidence concerns the gene IL6 and triple-A syndrome.
