Treatment group received supplementation with arachidonic acid (ARA) and docosahexaenoic acid (DHA) for 16 weeks.
ADI-R, Autism Diagnostic Interview- Revised; ABC, Aberrant Behavior Checklist.
1) Repeated measures analysis of variance (ANOVA) was used when baseline scores as a covariate with treatment as the between-subject-factor and test session repeated
factor, * P<0.05.
2) ADI-R algorithm item C 1: Encompassing preoccupation or circumscribed pattern of interest.
3) ADI-R algorithm item C 2: Apparently compulsive adherence to nonfunctional routines or rituals.
4) ADI-R algorithm item C 3: Stereotyped and repetitive motor mannerisms.
5) ADI-R algorithm item C 4: Preoccupation with parts of objects or nonfunctional elements of materials. |
