↵a P values were calculated using Fisher exact tests.
↵b Of the 797 aneurysms treated with the PED alone, data regarding the number of PEDs used were not available for 2 aneurysms treated; thus, 795 is used as the total denominator. Of these 795 aneurysms, size data were not available for 8 aneurysms. All 795 are included in the total calculation, but only 787 are included in the aneurysm-size categories.
↵c Of the 109 aneurysms treated with PED/coil, size data were not available for 2 aneurysms. All 109 are included in the total calculation, but only 107 are included in the aneurysm-size categories.
