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
In the present study, a new type of Caspase-1 homolog is identified from Crassostrea gigas (defined as CgCas1-2D). It is composed of 2×DSRM-CASc domain and has closer evolutionary relationship with mammalian Caspase-1s. The mRNA expressions of CgCas1-2D increase significantly after Vibrio splendidus or LPS stimulation. Recombinant CgCas1-2D and its 2×DSRM and CASc domains all bind various PAMPs and bacteria. rCgCas1-2D shows the highest binding activity to human Caspase-1 substrate. Upon recognizing bacteria, CgCas1-2D co-localizes and interacts with CgGSDME, while it has no cleavage activity to CgGSDME. CgCas1-2D inhibits the histone methylation and acetylation levels and CgNF-κB/Rel nuclear translocation mediated by CgGSDME. In addition, CgCas1-2D suppresses the mRNA expression levels of cytokines mediated by GSDME-NF-κB/Rel axis. The results demonstrate that a new type of anti-inflammatory Caspase-1 identified from oyster upon recognizing various bacteria interacts with GSDME to inhibit the histone modification and NF-κB signaling to suppress the inflammation.
