Puerarin alleviates burn-related procedural pain mediated by P2X(3) receptors.
Article in Purinergic signalling, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 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
Pain is a major problem after burns. Procedural pain evoked by burn dressing changes is common in patients, and its management is a critical part of treatment in acute burn injuries. Burn pain is very likely the most difficult form of acute pain to treat. ATP contributes to inflammation, and ATP is implicated in peripheral pain signaling via actions upon P2X(3) receptors. Puerarin is extracted from a traditional Chinese medicine and may act on P2X(3) receptor mechanisms. The Visual Analogue Scale (VAS) has been shown to be a sensitive indicator of pain intensity and treatment effects. Peripheral blood mononuclear cells (PBMCs) are involved in nociception or pain after burn injury. Burn patients were randomly divided into normal saline (NS) group (salt solution is saline) and puerarin-treated group and pain (Visual Analogue Scale scores) and inflammation (PBMCs) measured. Burn pain produces a stress response, so blood glucose, insulin, and cortisol levels in burn patients were determined. Furthermore, the expression of P2X(3) protein and mRNA in PBMCs was detected. The VAS scores in the puerarin-treated group were lower than those in NS group. The blood glucose, insulin, and cortisol levels in the puerarin-treated group at post-dressing changes were significantly decreased in comparison with those in NS group. The expression levels of P2X(3) protein and mRNA in PBMCs of burn patients in NS group were significantly increased in comparison with those in the puerarin-treated group. Puerarin can antagonize inflammatory factors (such as ATP) and decrease the upregulated expressions of P2X(3) protein and mRNA in PBMCs after burns to decrease VAS. Thus, puerarin had an analgesic effect on procedural pain in dressing changes of burn patients related to P2X(3) receptors.
