Clinical Analysis on Alteration of Thyroid Hormones in the Serum of Patients with Acute Ischemic Stroke

Table 2

Stroke outcome measured by National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS).

	Low T3 group	Normal T3 group
	(T3 ≤ 75 ng/dL)	(T3 > 75 ng/dL)
	$n=29$	$n=18$
The 1st day
Median value of NIHSS	11 (5~19)	6 (2$~$14)*
The 1st clinic follow-up
Median value of NIHSS	9 (2~17)	4 (0$~$9)*
Patients with any improvement ($\mathrm{\Delta }$NIHSS ≥ 2)	8 (27.6%)	12 (66.7%)*
Median value of mRS	3 (1~5)	1 (0$~$3)*
Patients with favorable outcome (mRS ≤ 1)	9 (31.0%)	10 (55.6%)*

Numbers in parentheses for nominal data indicate percentages and for continuous data indicate range of actual scores. *$P<.05$ is compared to low T3 group. The 1st day: on admission; The 1st clinic follow-up: outpatient follow-up usually occurred 2–4 weeks after discharge; $\mathrm{\Delta }$NIHSS $\ge$ 2: improvement when scores decreased ≥2 compared to baseline.
