Results of British ability scales (BAS-II) and NEPSY testing for study children without motor disability
| Variable | Comparison groupa (n = 49) | Moderate encephalopathyb (n = 32) | p Value (a–b) | Severe encephalopathyc (n = 18) | p Value (a–c) | p Value (b–c) |
|---|---|---|---|---|---|---|
| Results are mean (SD). Comparisons of BAS-II and NEPSY standardised scores were made using Student’s t test, and comparisons of memory subscales and everyday memory score using the Mann-Whitney U test. Comparisons were made between each encephalopathy group and comparison group ((a–b) and (a–c)) and between moderate and severe encephalopathy groups (b–c); significant differences are in bold. | ||||||
