The soar stroke score predicts inpatient and 7-day mortality in acute stroke

I think this is still a piece of shit. If you want to predict something you use objective measurements like CT, MRI and PET scans that show the dead and damaged areas in 3d. With that you could accurately correlate damage to death rates and recovery rates. And map therapies that helped in rehab.
And that would make therapies repeatable and lead to stroke protocols.
Does no one know how to think in the stroke world?

Kwok CS et al. – An accurate prognosis is useful for patients, family, and service providers after acute stroke. A simple score based on 4 easily obtainable variables at the point of care may potentially help predict early stroke mortality.
Methods

• They validated the Stroke subtype, Oxfordshire Community Stroke Project Classification, Age, and prestroke Rankin stroke score in predicting inpatient and 7–day mortality using data from 8 National Health Service hospital trusts in the Anglia Stroke and Heart Clinical Network between September 2008 and April 2011.

Results

• A total of 3547 stroke patients (ischemic, 92%) were included.
• An incremental increase of inpatient and 7–day mortality was observed with increase in Stroke subtype, Oxfordshire Community Stroke Project Classification, Age, and prestroke Rankin stroke score. Using a cut–off of >3, the area under the receiver operator curves values for inpatient and 7–day mortality were 0.80 and 0.82, respectively.
