[Neuropeptide effects on the trigeminal system: pathophysiology and clinical significance for migraine].
Review in Schmerz (Berlin, Germany), 2011. 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
Neuropeptides, such as calcitonin gene-related peptide (CGRP), substance P and vasoactive intestinal polypeptide (VIP) are considered important mediators in primary headaches. Increased concentrations of CGRP have been found in jugular venous plasma during attacks of migraine and, concomitant with VIP elevation, during cluster headache. Substance P and CGRP are produced from subsets of trigeminal afferents whereas VIP derives from parasympathetic efferents. Release of these neuropeptides in the meninges causes arterial vasodilatation, mast cell degranulation and plasma extravasation in animal experiments. Particularly CGRP seems to be important, as receptor antagonists have recently been shown to have a therapeutic effect on migraine. Animal models have confirmed the role of CGRP in meningeal nociception. The activity of spinal trigeminal neurons is a sensitive integrative measure of trigeminal activity and CGRP released from central terminals of trigeminal afferents in the spinal trigeminal nucleus has been shown to facilitate nociceptive transmission, most likely by a presynaptic action. The proposed CGRP functions are supported by the distribution of CGRP receptor components localized in the rat cranial dura mater, the trigeminal ganglion and the spinal trigeminal nucleus. The currently available data indicate multiple sites of CGRP action in trigeminal nociception and the pathogenesis of migraine but central CGRP receptors are probably the essential targets in the treatment of migraine using CGRP receptor antagonists.
