Example distributions of local 1st or maximum principal strains from aneurysmal and non-aneurysmal mouse aortae. a The aneurysmal aorta (left) shows a right-skewed strain distribution with a long tail of few large strains and a majority of small strain values (positive skewness = 1.191). b Conversely, the non-aneurysmal aorta displayed a left-skewed distribution with a long tail toward small strains and a majority of large strain values (negative skewness = $-$0.529). In aneurysmal aortae, only the strains of the aneurysmal section highlighted within the box were included in the evaluation. For non-aneurysmal aortae, we selected a corresponding section of suprarenal abdominal aorta
