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
After a status epilepticus (SE) event, the NACHT, LRR, and PYD domain-containing protein 3 (NLRP3) inflammasome is activated, accompanied by morphological alterations in microglia and astrocytes, which are key features of inflammation. Antioxidants have been shown to inhibit NLRP3 inflammasome activation and suppress glial cell morphological alterations. In this study, firstly we evaluated the antiseizure effect of the antioxidant edaravone (EDA) at different doses on the convulsive behavior and epileptiform activity induced by pilocarpine (Pilo) in order to determine the most appropriate dose for subsequent experiments. Later, for the main study, we investigated the temporal expression of NLRP3 inflammasome components and glial cell morphological characteristics following SE to assess the efficacy of the EDA, using a rat model of SE induced by Pilo and conducted a temporal analysis of the protein expression of NLRP3, IL-1β, caspase-1 p20 and IL-10 by nano dot blotting. Additionally, Sholl analysis was performed to evaluate glial cell morphology. Our findings revealed an increase in the expression of NLRP3 inflammasome components after SE, accompanied by glial cell morphological changes characteristic of a reactive state. Furthermore, EDA significantly reduced NLRP3 expression, decreased IL-10 levels and mitigated SE-induced morphological alterations in glial cells.
