Title: Ordinal tree model for predicting day-90 stroke outcome by modified Rankin Scale score (mRS) (n=4051). Legend: Each tree node contains day-90 mRS values: mRS of 0 = no symptoms; mRS of 1 = no significant disability; mRS of 2 = Slight disability; mRS of 3 = moderate disability; mRS of 4 = moderately severe disability; mRS of 5 = severe disability; mRS of 6 = death; B-NIHSSS=Baseline National Institutes of Health Scale score; B-SBP=Baseline systolic blood pressure; CHF=congestive heart failure
