 Memory, attention, and behaviour problems in young adults with CH and sibling controls*

OutcomeTests and questionnairesCH, n = 49 Mean (SD)Siblings, n = 41 Mean (SD)Estimated difference (95% CI)p‡Number/% of CH subjects with results <1 SD below sibling mean
SD, standard deviation; CI, confidence interval.
*Group differences are analysed with a linear mixed model adjusted for age and sex.
†High scores on this test or questionnaire indicate more problems than low scores.
‡p values are the original ones from the mixed model analysis. B marks those that are significant after Bonferroni correction.
