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
purposeTo determine the role of nuclear factor-κB (NF-κB) during FGF-2-mediated endothelial mesenchymal transformation (EMT) in response to interleukin (IL)-1β stimulation in corneal endothelial cells (CECs).
methodsExpression and/or activation of IL-1 receptor-associated protein kinase (IRAK), TNF receptor-associated factor 6 (TRAF6), phosphatidylinositol 3-kinase (PI 3-kinase), IκB kinase (IKK), IκB, NF-κB, and FGF-2 were analyzed by immunoblot analysis. Cell proliferation was measured by 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide (MTT) assay. NF-κB activity was measured by NF-κB ELISA kit, while binding of NF-κB to the promoter region of FGF-2 gene was determined by chromatin immunoprecipitation.
resultsBrief stimulation of CECs with IL-1β upregulated expression of IRAK and TRAF6 and activated PI 3-kinase; expression of IRAK and TRAF6 reached maximum within 60 minutes, after which the expression disappeared, while PI 3-kinase activity was observed up to 4 hours after IL-1β stimulation. Use of specific inhibitor to PI 3-kinase or IRAK demonstrated that IRAK activates PI 3-kinase, the signaling of which phosphorylates IKKα/β and degrades IκB, subsequently leading to activation of NF-κB. The induction of FGF-2 by IL-1β was completely blocked by inhibitors to NF-κB activation (sulfasalazine) or PI 3-kinase (LY294002), and both inhibitors greatly blocked cell proliferation of CECs. Chromatin immunoprecipitation further demonstrated that NF-κB is the transcription factor of FGF-2 as NF-κB binds the putative NF-κB binding site of the FGF-2 promoter.
conclusionsThese data suggest that IL-1β signaling combines the canonical pathway and the PI 3-kinase signaling to upregulate FGF-2 production through NF-κB, which plays a key role as a transcription factor of FGF-2 gene.
