Figure 2.

(A) The distribution of the modified Rankin Scale (mRS) scores of patients in the low, expected, and excessive unaccounted white matter hyperintensity (uWMH) burden groups. The proportions of mRS scores were shifted toward worse mRS scores for the higher uWMH burden groups. (B) The acute stroke severity subgroup analysis. The proportion of patients who achieved the full functional independence (mRS excellent: mRS 0 and 1) in each uWMH burden group was plotted in blue and in red for the mild [NIH Stroke Scale (NIHSS) <7] and severe (NIHSS ≥7) acute stroke severity groups, respectively.
