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
backgroundLiver regeneration is orchestrated by various cytokines and growth factors, and any imbalance in this process may contribute to liver disease development. Augmenter of Liver Regeneration (ALR), an anti-apoptotic and anti-inflammatory co-mitogen supports regeneration, yet the molecular mechanisms by which ALR regulates proliferation and inflammation remain poorly understood.
methodsHepatoma cell lines, primary mouse and human hepatocytes, and mice subjected to ischemia–reperfusion injury, were treated with recombinant ALR. Various specific inhibitors, small interfering RNA, immunoprecipitation, Western blot, qRT-PCR and ELISA techniques were utilized to analyze the underlying signaling pathways.
resultsALR induces the phosphorylation of the EGF-receptor (EGF-R), which subsequently activates the MAPK and PI3K/Akt pathways. EGF-R phosphorylation is triggered by EGF-R ligands, such as TGFα, amphiregulin and HB-EGF, which are released from plasma membranes by the sheddase a disintegrin and metalloproteinase 17 (ADAM17) upon ALR activation. Furthermore, ALR-activated ADAM17 cleaves the membrane-tethered IL-6-receptor α (gp80), thereby reducing IL-6-induced STAT3 phosphorylation and the expression of its target genes (e.g. ICAM-1) in vitro and in vivo. The induction of ADAM17 involves the phosphorylation of protein kinase C (PKC) and the tyrosine kinase Src, as well as the activation of a G protein-coupled receptor (GPCR) by ALR. ALR transduction across plasma membranes is achieved by activating a Gαq/11-coupled GPCR, which is known to induce ADAM17 via cytosolic relay molecules PKC and Src.
conclusionActivation of ADAM17 by ALR: i) transactivates EGF-R signaling upon release of membrane-bound EGF-R ligands, and ii) attenuates classical IL-6 signaling upon gp80 shedding. ALR supports liver regeneration by inducing EGF-R-dependent proliferative (MAPK) and anti-apoptotic (PI3K/Akt) pathways, and reduces IL-6-induced inflammatory gene expression.
