↵* p<0.05,
↵† p<0.01. Data with and without brackets represents spearman correlation coefficients of morphological risk factors in unruptured and ruptured aneurysms; correlation coefficient (R) ≥0.7 indicates strong correlation; 0.7-0.4 indicates moderate correlation, and <0.4 indicates weak correlation
