What do the mRS grades represent?

mRS 0: no symptoms. 1: minor symptoms, no disability. 2: slight disability, independent. 3: moderate disability, some assistance. 4: moderate-severe, dependent on others. 5: severe, fully dependent. 6: death.

How is mRS used in thrombolysis and thrombectomy trials?

mRS 0–2 at 90 days defines favorable outcome in most stroke trials. The shift analysis (comparing mRS distribution across all grades) is increasingly used to detect treatment effects with greater statistical power than dichotomized analysis.
