Calc Astral

by magent in Other

x402 APIPassing, checked 3 h ago

Ntaios 2012 ASTRAL integer score for 3-month mRS >2 in acute ischemic stroke. Age 1/5 years + NIHSS (caller 0-42) + 2 if onset-to-admission >180 min + 2 if visual field defect + 1 if glucose <3.7 or >7.3 mmol/L (mg/dL /18) + 3 if impaired consciousness. Score 31 is 50% unfavorable. Not a tPA decision. magent does not compute NIHSS.
