Table 3. Summary statistics for the associations between each of the TVA parameters (dependent variables) and each of the clinical measures.
Parameter | NIHSS | TOAST | location | ||

C | 0.408 (0.977) | 0.418 (0.678) | 0.109 | 1.937 (0.116) | 0.756 (0.523) |
t0 | 1.997 (1.723) | 1.159 (0.251) | 0.302 | 1.188 (0.325) | 0.740 (0.532) |
error rate | −0.003 (0.007) | −0.376 (0.708) | −0.098 | 0.310 (0.87) | 1.603 (0.198) |
Notes.
Significant after Bonferroni correction.
Main effect of TVA parameters on Cogmed performance.
K = short-term memory capacity; C = perceptual processing speed; t0 = perceptual threshold; NIHSS = National Institute of Health Stroke Scale; TOAST = Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification system; location = coarse four-class classification of lesion location (left hemisphere, right hemisphere, bilateral and brain stem/cerebellum lesions); Estimate = unstandardized regression coefficients b; std. error = standard error; t = t -value; p = p-value.
Cohens D was calculated using two times the tvalue divided by the square root of the degrees of freedom.
