Comparisons of the neuropsychological composite scores of the study groups
| Dependent variable | Composite z scores | Between-subjects effects | Pairwise contrasts | |||||||
|---|---|---|---|---|---|---|---|---|---|---|
| SIVD | OS | NC | F | p value | ηp2 | SIVD v OS | SIVD v NC | |||
| Mean (SD) | Mean (SD) | Mean (SD) | p value | ηp2 | p value | ηp2 | ||||
| MANCOVA F adjusted for age and education. All pairwise comparisons were also significant after Bonferroni correction except for the delayed recall score between SIVD and OS groups. Effect size is expressed as partial eta squared (ηp2). | ||||||||||
| NC, normal control subjects; OS, other stroke patients; SD, standard deviation; SIVD, subcortical ischaemic vascular disease. | ||||||||||
