Review in Current pain and headache reports, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled it.

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

Some studies suggest that platelet activation and aggregation are associated with migraine, likely secondary to changes occurring during the acute attack. Evidence also suggests that platelet clots can lodge in small cerebral vessels, and that the resultant ischemia and inflammation can induce cortical spreading depression with aura-like symptoms and pulsatile headache. Endothelial dysfunction, a result of numerous vascular, genetic, and environmental risk factors, is more common in women with migraine and leads to altered hemostasis. When associated with other factors, such as oral contraceptive use, there may be an increased tendency for thrombus formation, secondary migraine with aura, transient ischemic attacks, and stroke. Identifying those migraineurs at highest risk of developing endothelial dysfunction and platelet disorders may allow for preventive strategies to avoid the cerebral consequences.
