The question behind the headline
Randomized trials involving autistic participants, often children; symptom scales vary.
What the finding does—and doesn’t—tell us
Findings on one symptom do not generalize to all experiences of autism. Modest pooled changes do not imply that omega-3 treats autism itself.

Three questions to take forward
- Was the study population similar to the person or situation I have in mind?
- Did it measure an outcome people feel or experience, or only a laboratory marker?
- How do formulation, usual care, absolute benefit and adverse effects change the interpretation?
