The effects of Valerian on sleep spindles in a model of neuropathic pain.
Article in Sleep science (Sao Paulo, Brazil). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
introductionMATERIAL AND
methodsThe present study was conducted to investigate the effects of Valerian extract (VAL) on sleep spindles and induced anxiety in chronic neuropathic pain model in rats. 24 male rats were divided into three groups: neuropathic group (n=9) in which the rats underwent chronic constriction injury (CCI), sham group (n=7) in which the sciatic nerves of the animals were exposed without any constriction and also fed with the vehicle, and the third group was under CCI condition and treated with Valerian (n=8). All the rats underwent electrode implant surgery so that we could record electroencephalogram and electromyography waves. In all the three groups, EEG and EMG recordings were recorded three times (150min each time). The initial recording was just prior to the CCI surgery and the rest were 3 and 6 days following CCI surgery. Moreover, cold allodynia and elevated plus maze tests were performed 3 and 6 days following the CCI surgery.
resultsValerian treatment could repair the allodynia induced by neuropathy. On the other hand, by Valerian treatment (400mg/kg) during neuropathy, the REM sleep, decreased and the non-REM sleep increased. Moreover, there was an increment in sleep spindle density and spindle frequency even in neuropathic condition. DISCUSSION: This herbal supplement improves the quality of sleep in neuropathy conditions.
