Table 1:

The mean value, standard error, maximum, and minimum values of all geometric indices and biomechanical parameters (PWS, 99thWS and SAWS are for the non-uniform wall thickness AAA models while PWS’, 99thWS’ and SAWS’ are for the uniform wall thickness AAA models). The 13 indices about wall thickness are indicated by “*” and will not be considered in the AAA model with uniform wall thickness.

The definition and mathematical formulation of the geometric indices are included in the Supplementary Material, while the biomechanical parameters are defined in section 4.2. The following are the most commonly used acronyms from this table: Dmax (maximum transverse diameter); Dneck,p (proximal neck diameter); Hb (bulge height); dc (distance between the lumen centroid and the centroid of the cross section where Dmax is located); THDmax (average wall thickness where Dmax is located); THminvar (minimum variance of the wall thickness); DHr (diameter-height ratio); β (asymmetry factor); T (tortuosity); Cave (average lumen compactness); IPR (isoperimetric ratio); NFI (non-fusiform index); GAA (area averaged Gaussian curvature).
