  1. Data for entire patient sample (n = 41) is shown
  2. a Lesion volumes are shown as mean (SD) and range
  3. b Correlation between mean lesion volume of a Region and Fugl-Meyer motor impairment scores (Values are Spearman rank correlation coefficients, with p-values in brackets)
  4. c Region 1 represents the lesion core
  5. d Region 2 represents the peri-necrotic tissue
  6. e Region 3 represents lesions in the same hemisphere as index stroke
  7. f Region 4 represents lesions in the opposite hemisphere
  8. * Significant at p < 0.05
