Luminal soluble elastin fragment concentration with respect to age and aneurysm size. A, Relationship between soluble elastin fragment (sELAF) concentration and age in ruptured aneurysms (R ²=0.07; P=0.06). B, Relationship between concentration of sELAF and aneurysm size in ruptured aneurysms (R ²=0.02; P=0.33). C, Relationship between concentration of sELAF and age in unruptured aneurysms (R ²=0.00007; P=0.96). D, Relation between concentration level of sELAF and aneurysm size in unruptured aneurysms (R ²=0.002; P=0.78). R indicates correlation coefficient; β, slope of regression line.
