COMP and triple-A syndrome: Moreover, compared with the highest tertile of plasma COMP levels (≥ 279.9 ng/mL), the odds ratios for the risk of AAA for the middle (213.8–279.9 ng/mL) and lowest tertiles (< 213.8 ng/mL) were 57.954 (95% CI: 7.449–450.881) and 42.268 (95% CI: 4.354–410.303), respectively (Supplementary information, Table S2).
