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
Interferon-induced protein with tetratricopeptide repeats (IFIT) 2 is associated with various viral infections and pathogenesis in humans and mice. However, there are few reports on IFIT2 in pigs and the polymorphic information remains unclear. Here, by using a direct PCR sequencing method, we identified four single nucleotide polymorphisms (SNPs), c.259G>A (p.Gly87Ser), c.520T>G (p.Phe174Val), c.571C>T (p.Pro191Ser), and c.879A>G (p.Glu293Glu), for the first time in the coding sequence of the porcine (p) IFIT2 gene from a Chinese local breed (Hebao pig), Western commercial pig breeds (Yorkshire and Landrace), and a Chinese developed breed (Beijing Black pig). SNP c.520T>G (p.Phe174Val) leads to the addition of a tetratricopeptide repeat motif, characteristic structure of the IFIT family. SNPs c.259G>A and c.520T>G are medium polymorphic loci (0.25 < polymorphic information content < 0.5) and distributed differently in Western pig breeds and the Chinese local pig, Hebao, which is well known for its strong resistance to disease. Additionally, they are completely linked. The four SNPs constituted five haplotypes with GTCA and AGCA as dominant. The haplotype variant AGCA, which is mainly present in Hebao pigs, significantly synergized the poly(I:C)-induced activation of transcription factors, including NF-κB and IFN-stimulated response element (ISRE)-binding factors, and the expression of interferon β, indicating that the variant contributes to the induction or magnitude of the immune response upon viral infection. The data showed that variant AGCA might be useful in improving the resistance of pigs to viruses through marker-assisted selection.
