Table 2 Association of motor impairment scores with the mean individual and cumulative lesion volumes for each region

From: Correlating lesion size and location to deficits after ischemic stroke: the influence of accounting for altered peri-necrotic tissue and incidental silent infarcts

Lesion Type: Lesion Volume,a cm3 Correlation Between Impairment Score and Lesion Volume (p-value)b
Region 1 c 15.9 (30.7) 0.09 - 126.2 -0.35 (0.025)*
Region 2 d 4.1 (6.6) 0.0 - 28.5 -0.28 (0.10)
Region 3 e 0.058 (0.051) 0.0 - 0.17 0.029 (0.86)
Region 4 f 0.63 (1.1) 0.0 - 3.9 0.005 (0.98)
Region 1 + 2 19.6 (36.7) 0.12 - 154.7 -0.35 (0.028)*
Region 1 + 2 + 3 19.6 (36.2) 0.12 - 154.7 -0.34 (0.030)*
Region 1 + 2 + 3 + 4 19.9 (36.6) 0.20 - 154.7 -0.34 (0.032)*
  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
