MPO and triple-A syndrome: After backward elimination, only sex (odds ratio 2.598 and 95% CI [1.01–6.71]), ICA stenosis (odds ratio 46.43 and 95% CI [18.95–130.3]), and PAD (odds ratio 8.09 and CI [3.28–20.78]) had significant independent importance for AAA diagnosis, whereas MPO had no significant independent importance for AAA diagnosis (odds ratio 1.0001 and CI [0.99–1.01], p = 0.638) (Supplementary Table S2).
