205 Neuropsychological outcome (survival and PCPC at hospital discharge). The SES was calculated using a ‘Status Score’ divided into tertiles to interpret a ‘low status’, middle status’ and ‘high status’ (13) . The ‘Status Score’ is based on income, education level and unemployment rate by postal code. Outcomes measures Functional outcomes The following functional outcomes were assessed: PCPC score, school attendance, motor deficits and epilepsy. PCPC scores were dichotomised into ‘good’ outcome (score 1 and 2) or ‘poor’ outcome (scores 3 to 6) (6) . All PCPC scores were determined by a paediatric neurologist (MH). Neuropsychological outcomes Validated, age-appropriate neuropsychological tests and questionnaires with Dutch normative testdata were used to assess a broad range of neuropsychological domains, see supplementary file 2 for detailed description. 1. Development and intelligence in children (all ages): age-appropriate versions of the Bayley Scales of Infant Development or the Wechsler Scales (BSID-II, Bayley- III, WPPSI-III, WISC-III or WAIS-IV) (14-17) . 2. Selective attention: Stroop Color Word Test ( ≥ 8 years) (18) . 3. Sustained attention: Bourdon-Vos cancellation test ( ≥ 6 years) (19) . 4. Processing speed: from the Wechsler Scales (WPPSI-III, WISC-III or WAIS-IV) ( ≥ 4 years) (14-16) . 5. Visual motor integration: Beery Developmental Test of Visual Motor Integration (Beery-VMI) ( ≥ 2 years) (20) . 6. Verbal memory: Rey auditory verbal learning test (Rey-AVLT), delayed recall ( ≥ 6 years) (21, 22) . 7. Visual memory: Rey-Osterrieth complex figure test (Rey-CFT) recognition ( ≥ 6 years) (23) . 8. Executive functions (cognitive flexibility): Trail-Making Test part B ( TMTB) ( ≥ 8 years) (24) . 9. Parent-reported executive function: Behaviour Rating Inventory of Executive Function questionnaires (BRIEF-P or BRIEF) ( ≥ 2 years) (25) . 7
