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

Cutaneous allodynia (CA), the perception of pain when a non-noxious stimulus is applied to normal skin, has been described in various pain syndromes. The pathophysiology of CA in headache is thought to be related to central sensitization of brainstem, and possibly thalamic, neurons. The recognition of CA in cluster headache (CH) is recent, and available data are scant. Some studies suggest the occurrence of CA in a significant proportion of CH patients. However, one study that examined sensory thresholds in CH failed to confirm this. CA in CH is characterized by rapid onset and termination, suggesting different mechanisms compared with CA in migraine. CA in CH is common in trigeminal areas but may spread to cervical dermatomes and beyond. The relations between the type of CH (episodic vs chronic) and CA are unknown. Further studies are needed to determine the mechanism of CA in CH, and its clinical implications.
