Associations Between Fatty Acid Levels in Human Blood and Trigeminovascular Tissues.
Article in Lipids, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) are precursors to oxylipins that modulate pain and inflammation. We previously demonstrated that (1) a dietary intervention increasing omega-3 and reducing omega-6 PUFAs alters the concentration of these oxylipin precursors in blood, and (2) these changes are associated with reduced headache pain in humans. However, the extent to which blood levels reflect trigeminovascular tissues remains unclear. We sought to determine whether oxylipin precursor PUFA levels in blood reflect those in the meninges, cranial arteries, and trigeminal ganglia. Precursor PUFA compositions of post-mortem blood and trigeminovascular tissue specimens from 70 individuals, procured from the Human Brain Collection Core at the National Institute of Mental Health, were quantified. Regression models adjusted for confounders examined relationships between blood and tissue PUFA levels. Eicosapentaenoic acid in blood was associated with levels in cranial arteries, meninges, and trigeminal ganglia [logged coefficients (p value): 0.29 (0.019); 0.37 (< 0.001); 0.25 (0.009)]. Other PUFAs, including linoleic acid, arachidonic acid, n-6 docosapentaenoic acid, and docosahexaenoic acid, also showed significant associations between blood and meninges and/or trigeminal ganglia levels. These findings support using blood measurements of certain PUFAs as a proxy for their concentration in tissues directly involved in headache pathogenesis.
