Determinants for CA collagen age. A) Estimated collagen age for patients with ruptured and unruptured CAs. Open circles denote outliers, filled circles denote extreme outliers in panel A and B. B) Estimated CA collagen age for patients with and without a history of risk factors for aneurysm formation and rupture. Open circles denote outliers, filled circles denote extreme outliers in panel A and B. C, D) Correlation of patient age with estimated CA collagen age or actual F14C levels in CA collagen, respectively. Correlations remained significant after exclusion of the extreme outlier.
