DRAGON (Strbian 2012 Neurology) for 3-month outcome after IV thrombolysis

DRAGON (Strbian 2012 Neurology) for 3-month outcome after IV thrombolysis. CT hyperdense artery or early infarct 0/1/2, prestroke mRS >1 (1), age <65/65-79/>=80 (0/1/2), glucose >8 mmol/L (mg/dL /18) (1), onset-to-treatment >90 min (1), NIHSS 0-4/5-9/10-15/>15 (0/1/2/3); max 10. Tabulated mRS 0-2 and mRS 5-6 percents for scores 0-1, 2, 3, 8, and 9-10 only. Not a tPA decision. Not studied in basilar occlusion. magent does not read CT or assign NIHSS.
