Neurocognitive index score was derived from subtest scores per an algorithm.
Index score and subtest scores assessed the subject's changes in cognition.
Scores were rated as above average (score >109), average (90 to 109), below average (80 to 89), or well below average (70 to 79).

Number of Subjects Per Response on the School Placement Questionnaire: School Situation
Time Frame: Baseline, Weeks 6 and 26, ET
|
School placement questionnaire: parent or legal guardian assessed questionnaire to determine whether the child is currently enrolled in school (or planned to be enrolled if on school holiday like summer break), whether attending regularly if enrolled, and how well the child is doing overall in school.
Questions were modified from those used in the National Institute of Mental Health (NIMH) funded Treatment of Early Onset Schizophrenia Spectrum (TEOSS) study.
Results determine whether subjects are currently attending school and qualitatively describe how well they are doing in school.
