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
The stimulator of interferon genes (STING) is a pivotal regulator of type I interferon (IFN) responses. Although the IFN system is confined to vertebrates, STING is present across metazoans and in some unicellular eukaryotes, suggesting involvement in distinct functions prior to vertebrate divergence. Here we explore the conservation of STING-mediated regulation of polyunsaturated fatty acid (PUFA) metabolism. We find that STING homologs from vertebrates, invertebrates, and unicellular eukaryotes interact with fatty acid desaturase 2 (FADS2), the rate-limiting enzyme in PUFA metabolism, and influence subsequent functional outputs. Specifically, we show that STING homologs differentially shape cell susceptibility to infection by DNA and RNA viruses independently of the activation of IFN responses, suggesting that STING-mediated metabolic pathway regulation may participate in primitive host defense mechanisms. Thus, we identify STING-mediated metabolic regulation as an evolutionarily conserved feature and a primordial function of STING.
