Epidemiologic and anatomic aspects comparing incidental and ruptured intracranial aneurysms: A single centre experience

Percentage of aneurysm locations, comparing the pooled data underlying the PHASES score (incidental n = 8162, ruptured n = 220) with the present cohort (incidental n = 200, ruptured n = 197). Asterisks mark significant differences between the two datasets. Fisher’s exact test * p < 0.05, **p < 0.005, ***p < 0.0005.
