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

Post-traumatic headache (PTH) is a common and well-recognized entity. Tension-type headache and migraine are the commonest phenotypes that can result from head trauma, while the onset of cluster headache (CH) in close temporal relation to a head trauma has only been described in rare cases. Nevertheless, CH patients seem to incur more frequent traumatic head injuries during their lifetimes when compared to migraine controls and the general population. The basis of this association remains unclear, since only a limited number of methodologically robust studies have examined it. However, three main hypotheses can be proposed to explain this association: head trauma is the direct cause of CH; head trauma is a risk factor for the future development of CH; and head trauma is a consequence of a CH trait. A better understanding of the association between head trauma and CH may provide important insights into both the pathophysiology of CH and the mechanisms by which traumatic head injury predisposes patients to developing headaches.
