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

Cervical dystonia (CD) is often associated with pain in the neck muscles, though the mechanisms underlying pain in this condition are still largely unknown. The aim of this study was to assess laser pain rating and CO(2) laser-evoked potentials (LEPs) in CD patients with pain in the posterior neck region. We assessed the N2/P2 LEP complex and laser pain rating in a group of 20 CD patients and in 21 normal subjects. In 11 of the 20 CD patients (group I), the N2/P2 complex was recorded after stimulation of the skin overlying the right and left deltoid muscles (painless and non-dystonic). In the remaining nine CD patients (group II), the N2/P2 complex was recorded after stimulation of the skin over the splenius capitis muscle (painful and dystonic) and after stimulation of the skin overlying the contralateral splenius muscle (painless and non-dystonic). In group I patients, the N2/P2 LEP amplitude and laser pain rating after stimulation of both shoulders did not differ significantly from those obtained in normal subjects. Similarly, in group II patients, the N2/P2 LEP amplitude and laser pain rating after stimulation of the painful and dystonic splenius capitis muscle did not differ significantly from those obtained from either the contralateral painless, non-dystonic splenius capitis or normal subjects. The results of this study demonstrate that cutaneous nociceptive pathway function in CD patients is normal, thereby indicating that muscle pain in CD is not associated with any central sensitization of nociceptive inputs in either painful (dystonic) or non-painful (non-dystonic) body areas.
