1 · What the graph read from it

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.

2 · The registry

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

BACKGROUND AND

aimThe pathogenesis of the pain that occurs in episodic migraine attack is due to the activation of the trigeminal system's first neuron receptors located on vessel wall. The release from the endothelium of nitric oxide, a product of arginine metabolism, causes vasodilation and stretching of the vascular trigeminal system and promotes pain. It is unknown whether this same metabolic event is involved in the pain accompanying chronic migraine. To understand the possible role of arginine in the pathogenesis of chronic migraine patients, we evaluated the metabolism of arginine in plasma of chronic migraine and control subjects.

methodsWe evaluated the metabolism of arginine in a group of patients affected by chronic migraine. Quantification of arginine, ornithine, citrulline, monomethyl arginine (NMMA), dimethylarginines (ADMA, SDMA), and tyramine was performed by ultra-performance liquid chromatography coupled with a triple quadrupole mass spectrometer.

resultsChronic migraine patients showed low plasma levels of arginine, significantly elevated levels of ornithine, ADMA, and NMMA whereas the levels of citrulline and SDMA were in the range of controls.

conclusionsThe elevated levels of ADMA and NMMA, inhibitors of nitric oxide synthase, suggest that the metabolism of arginine may be inhibited with a possible reduction of NO release in the circulation of chronic patients. This suggests that the origin of pain may not be related to the vasodilation of trigeminal vascular system that occurs in episodic migraine patients.
