Figure 2. Association between pre-stroke and 90 day modified Rankin Scale (mRS) scores of nonagenarians and younger patients.

Figure 2

(A) Nonagenarians had higher pre-stroke as well as 90 day mRS scores as compared to younger patient. However, there was no difference in the rate of magnitude of mRS worsening between the two groups (data are mean ± 95% confidence intervals). (B) Nonagenarians had an overall similar 90 day mRS compared to younger patients when stratified by the pre stroke mRS category (P>0.05; data are mean±s.e.m.). Analysis of the 90 day mRS score distribution according to the pre stroke mRS score categories shows that (C) patients under the age of ninety achieved a favorable outcome even when having a pre stroke mRS of 3. (D) Conversely, among nonagenarians essentially only those achieved a favorable outcome who had no or only mild pre stroke functional deficits.
