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
backgroundRecently, we have reported an isatin-derived carbohydrazone, 5-chloro-N'-(6-chloro-2-oxoindolin-3-ylidene)-2-hydroxybenzohydrazide (SIH 3) as dual nanomolar FAAH (fatty acid amide hydrolase)-MAGL (monoacylglycerol lipase) inhibitor with good CNS penetration and neuroprotective activity profile. In this study, we further investigated the pharmacological profile of compound SIH 3 in the neuropathic pain model along with acute toxicity and ex vivo studies.
methodsChronic constrictive injury (CCI) was used to induce neuropathic pain in male Sprague-Dawley rats and the anti-nociceptive activity of the compound SIH 3 was investigated at 25, 50, and 100 mg/kg ip. Subsequently, locomotor activity was measured by rotarod and actophotometer experiments. The acute oral toxicity of the compound was assessed as per the OECD guidelines 423.
resultsCompound SIH 3 showed significant anti-nociceptive activity in the CCI-induced neuropathic pain model without altering the locomotor activity. Furthermore, compound SIH 3 showed an excellent safety profile (up to 2000 mg/kg, po) in the acute oral toxicity study and was also non-hepatotoxic. Further, ex vivo studies revealed that the compound SIH 3 produces a significant antioxidant effect in oxidative stress induced by CCI.
conclusionOur findings suggest that the investigated compound SIH 3 has the potential to be developed as an anti-nociceptive agent.
