Table 3.

MTR(15.6 ppm) intensity values in the ischemic lesion and the contralateral normal white matter (CNWM) among four stages (%; mean value ± SE).

Variable	Hyperacute stage	Acute stage	Early subacute stage	Late subacute stage	Analysis of variance P value
Lesion	26.61 ± 0.89	26.30 ± 0.99	25.39 ± 1.08	23.63 ± 2.58	0.625
CNWM	31.14 ± 1.15	31.08 ± 0.77	30.91 ± 1.92	29.36 ± 1.89	0.840
t-Test P valuesa	0.031	<0.001	<0.001	0.036

^at-Test P values corresponded to the results between MTR(15.6 ppm) values in the ischemic lesion and the CNWM. Bold indicates a significant change.
