Figure 4. Group 3(yellow line) NIHSS scores at the time of the acute or subacute phase (<3 days), early chronic phase (8–14 days) and outcome (30–60 days) are significantly higher than those of Group 1 (black line) and Group 2 (red line). NIHSS scores of Group 1 were significantly lower than those of Group 2 at the acute phase or early subacute phase, and those of Group 2 were significantly lower than those of Group 3. NIHSS scores of Group 1 were significantly lower than those of Group 2 at outcome.
