Endovascular Thrombectomy preceded by intravenous Alteplase versus endovascular Thrombectomy alone in Han Chinese patients treated for acute ischemic stroke with large vessel occlusion: a single-center retrospective analysis

Table 4 Functional and imaging outcome measures after endovascular thrombectomy with/ without intravenous alteplase intervention

Outcome measure			Cohorts		Comparisons
Outcome measure			EA cohort	ET cohort	Comparisons
Treatment(s)			Endovascular thrombectomy + intravenous alteplase intervention	Endovascular thrombectomy	p-value
Death within 90 days			28 (15)	24 (17)	0.761
Numbers of survivors with ≥95 the Barthel Index score at 90 days			75 (48)	63 (54)	0.392
Imaging outcomes	Successful reperfusion before thrombectomy		7 (4)	8 (6)	0.438
	Reperfusion of survivors after one-day	0	13 (7)	15 (11)	0.124
		1	02 (1)	5 (4)
		2a	27 (15)	13 (9)
		2b	58 (32)	33 (24)
		2c	35 (19)	34 (24)
		3	45 (25)	40 (29)
	Recanalization of survivors after 3 days	0	64 (36)	55 (39)	0.381
		1	40 (22)	35 (25)
		2	32 (18)	27 (19)
		3	44 (24)	23 (16)
	The final lesion volume of survivors at the discharge of hospital (mL)	Minimum	10	10	0.203
		Maximum	100	100
		Mean ± SD	42.15 ± 13.18	40.22 ± 11.18

Constant and ordinal variables are demonstrated as frequency (percentages) and continuous variables are demonstrated as mean ± standard deviation (SD)
Unpaired t-test was (for continuous variables) and Fischer exact test or the Chi-square test of Independence (for constant and ordinal variables) were performed for statistical analyses
Results were significant if p-value < 0.05
