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

The signal transduction modulator Rgs9-2 (Regulator of G protein signaling 9-2) plays a key role in dopaminergic and opioidergic transmission in the striatum. Rgs9-2 is a potent modulator of opiate reward and analgesia, but its role in chronic pain remains unknown. Here, we use the spared nerve injury model (SNI), to evaluate the influence of Rgs9-2 in sensory symptoms, as well as in anxiety and depression-like behaviors observed under neuropathic pain conditions. Our data demonstrate that knockout of the Rgs9 gene reduces the intensity of thermal hyperalgesia and mechanical allodynia the first few days after nerve injury. This small, but significant effect is only observed at early time points after nerve injury, whereas after the first week of SNI, Rgs9 knockout (Rgs9KO) and Rgs9 wildtype (Rgs9WT) mice show similar levels of mechanical allodynia and thermal hyperalgesia. Furthermore, Rgs9-2 deletion exacerbates anxiety and depression like behaviors several weeks after the emergence of the neuropathic pain symptoms. Our findings also reveal a temporal and regional regulation of Rgs9-2 protein expression by neuropathic pain, as Rgs9-2 levels are reduced in the spinal cord a few days after nerve injury, whereas decreased Rgs9-2 levels in the Nucleus Accumbens (NAc) are only observed several weeks after nerve injury. Thus, adaptations in Rgs9-2 activity in the spinal cord and in the NAc may contribute to sensory and affective components of neuropathic pain.
