Influence of collagen optical density (OD) and patient age on aortic wall mechanical parameters as recorded by the symmetry-constraint Compact Tension (symconCT) test. (a, b, c) Peak load. (d, e, f) Fracture energy. (g, h, i) Normalized clamp displacement at peak load. Blue dot: Data from TAV patients. Red dot: Data from BAV patients. Black dot: Data from QAV patient. Black lines: analysis of BAV and noBAV cases when merged. The analysis is based on linear mixed-effects modelling (LME) with confidence bounds indicated by dashed lines. The \({R}^{2}\) is adjusted by the number of fixed effects. (P: porcine; H: human; ax: axial loading; circ: circumferential loading; control: normal aortic tissue; col: collagenase-treated tissue, ela: elastase-treated tissue; BSA: body surface area). Given human data, the p-value refers to the influence of the variable in the x-axis on the y-axis.
