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
objectiveDiabetic neuropathic pain (DNP) is one of the common complications in type 2 Diabetes Mellitus (DM) patients. However, molecular mechanisms in underlying diabetic neuropathic pain are still poorly understood. Kalirin-7, a multifunctional Rho GDP/GTP exchange factor, located at the excitatory synapses, was reported to modulate the neuronal cytoskeleton. Therefore, in this study, we explored the effects of Kalirin-7 on type 2 diabetic neuropathic pain and the mechanisms in spinal cord in rats.
methodsThe type 2 diabetic neuropathic pain model was established in rats by feeding them with a high-sugar and high-fat diet for 8 weeks, and then fasting them for 12 hours, followed by a single intraperitoneal injection of STZ. Kalirin-7 was knocked down in the spinal cord by an intrathecal administration of Kalirin-7 siRNA.
resultsThe levels of Kalirin-7, p-NR2B and PSD-95 as well as the PSD-95-NR2B coupling were significantly increased in the spinal cord of type 2 DM rats. The knockdown of Kalirin-7 expression in the spinal cord by the intrathecal administration of Kalirin-7 siRNA not only reduced the levels of p-NR2B and the PSD-95-NR2B coupling in the spinal cord, but also relieved mechanical allodynia and thermal hyperalgesia in type 2 DM rats.
conclusionsOur findings suggest that spinally expressed Kalirin-7 likely contributes to type 2 diabetic neuropathic pain through regulating the PSD-95/NR2B interaction-dependent NR2B phosphorylation in the spinal cord.
