Stroke subjects who at 7 days after admission showed mean serum levels of TNF-α >20 pg/mL showed a mean NIHSS of 17.5 ± 1.0, those with mean serum levels of IL-1β >7 pg/mL showed a mean NIHSS of 17.8 ± 1.8, and those with mean serum levels of Il-6 >9 pg/mL showed a mean NIHSS of 18.0 ± 1.4, whereas patients who at 7 days after admission showed mean serum levels of TNF-α <20 pg/mL showed a mean NIHSS of 12.8 ± 1.7, those with mean serum levels of IL-1β <7 pg/mL showed a mean NIHSS of 10.1 ± 1.5 and those with mean serum levels of IL-6 <9 pg/mL showed a mean NIHSS of 11.3 ± 1.6. This evidence concerns the gene IL1B and Stroke.
