Summary of univariate comparison of morphological and hemodynamic parameters by locations. R and U indicate significantly positive and negative association of the variable with aneurysm rupture, respectively. Asterisks refer to significant difference after adjustment for multiple testing. Empty cells indicate no statistically significant difference. ALL refers to the results when combining aneurysms from all locations for the analysis.
