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

Cortical spreading depression (CSD) is a wave of neuronal depolarization thought to underlie migraine aura. Calcitonin gene-related peptide (CGRP) is a potent vasodilator involved in migraine pathophysiology. Evidence for functional connectivity between CSD and CGRP has triggered scientific interest in the possibility that CGRP antagonism may disrupt vascular responses to CSD and the ensuing plasma protein extravasation (PPE). Using imaging tools that allow us to generate continuous, live, high-resolution views of spatial and temporal changes that affect arteries and veins in the dura and pia, we determined the extent to which CGRP contributes to the induction of arterial dilatation or PPE by CSD in female rats, and how these events are affected by the anti-CGRP monoclonal antibody (anti-CGRP-mAb) fremanezumab. We found that the CSD-induced brief dilatation and prolonged constriction of pial arteries, prolonged dilatation of dural arteries and PPE are all unaffected by fremanezumab, whereas the brief constriction and prolonged dilatation of pial veins are affected. In comparison, although CGRP infusion gave rise to the expected dilatation of dural arteries, which was effectively blocked by fremanezumab, it did not induce dilatation in pial arteries, pial veins, or dural veins. It also failed to induce PPE. Regardless of whether the nociceptors become active before or after the induction of arterial dilatation or PPE by CSD, the inability of fremanezumab to prevent them suggests that these events are not mediated by CGRP, a conclusion with important implications for our understanding of the mechanism of action of anti-CGRP-mAbs in migraine prevention.
