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

introductionAnimal experimental evidence suggests that mechanisms of pain generation and response to treatment differ between neuropathic pain in the cephalic and the extracephalic innervation territories.

objectivesThe objective of the study was to examine whether in humans an identical peripheral painful neuropathy is associated with different pain qualities and sensory abnormalities in the face as compared with the thoracic region.

methodsWe retrospectively analysed epidemiological and clinical data of 639 patients with postherpetic neuralgia (PHN) in the face and at the trunk who were collected within a cross-sectional cohort survey and compared the respective sensory symptom profiles captured with the painDETECT questionnaire.

resultsTwo hundred twenty-four patients suffered from trigeminal PHN and 415 from thoracolumbar PHN. There were no significant differences in sex-ratio, age, body mass index, and pain duration. Patients with trigeminal PHN were more often severely depressed. Anxiety and sleep scores were not different. The average pain intensity was slightly higher in thoracolumbar PHN than trigeminal PHN (visual analogue scale 5.0 vs 4.6). Postherpetic neuralgia in the thoracolumbar region showed significantly more intense burning sensations, allodynia, painful attacks, and significantly less prickling and numbness than PHN in the face.

conclusionsThe differences in sensory symptom profiles between facial PHN and truncal PHN might be associated with different pathophysiological mechanisms and different treatment response. Drugs that primarily act on sensitization processes in the peripheral nociceptive system may work better in thoracolumbar PHN than in trigeminal PHN. If new medications are tested in patients with PHN, it would therefore be of interest to include an analysis of the treatment results in regard to subgroups based on the localisation of pain in patients with PHN.
