The question behind the headline
Adults with migraine; diets changing EPA/DHA and sometimes linoleic acid.

A network ranking is not a direct head-to-head test against every migraine medicine. Headache days, pain intensity and quality of life are separate outcomes.

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?
