Relationship between homocysteine level and prognosis of elderly patients with acute ischemic stroke treated by thrombolysis with recombinant tissue plasminogen activator

Table 1 Comparison of National institute of Health Stroke Scale scores between the two groups before and after the treatment (n = 60)

Groups	Before treatment	1 h after treatment	12 h after treatment	24 h after treatment
High-level group	13.25 ± 3.56	10.26 ± 2.56	6.89 ± 1.96	5.12 ± 1.56
Low-level group	9.56 ± 2.65	7.56 ± 1.56	6.22 ± 2.02	4.84 ± 1.26
t	6.440	6.976	1.844	1.082
P	0.000	0.000	0.068	0.282
