Neurocognitive outcomes (Table 2):
The primary outcome assessed in this study was the full scale intelligence quotient (FSIQ). The mean FSIQ of the entire sample population was 86.1 ± 20.5. The prevalence(95% confidence interval) of significant neurocognitive deficits(FSIQ <90) in the sample population was 50%(38% - 62%), with 18 children having extremely low FSIQ(25.7%), 7 with borderline FSIQ (10.0%) and 10 with low average FSIQ(14.3%).
