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
backgroundLung cancer is the most revenant and deadly tumors around the world. Here we aimed to explore the effects of hepatocyte nuclear factor 1B (HNF1B) and PCDHA13 overexpression on PI3K/AKT phosphorylation and malignant biological behavior in lung cancer A549 cells.
methodsHNF1B and PCDHA13 were amplified, and their overexpression plasmids were constructed for transfection. RT-PCR was used to detect the mRNA levels of HNF1B and PCDHA13. Cell proliferation and cell apoptosis were detected by clone formation experiments and flow cytometry, respectively, while cell invasion was studied by Transwell assay. The expression of survivin, PCNA, Caspase-3, Caspase-9, VEGF, and fibronectin was detected using immunoblotting, as was PI3K/AKT phosphorylation.
resultsThe level of HNF1B mRNA expression was significantly higher in the pcNDA-HNF1B group than in the control group (P<0.05), and the level of PCDHA13 mRNA expression in the pcNDA-PCDHA13 group was also significantly increased (P<0.05). The clone formation rate and cell invasion count in pcNDA-HNF1B or pcNDA-PCDHA13 transfected groups were significantly reduced in comparison with the control group, which were further validated with the protein expression levels of survivin, PCNA, VEGF, and fibronectin (P<0.05). However, the apoptosis rate, and the cleaved caspase3/caspase3 and cleaved caspase9/caspase9 protein expression ratios were all significantly increased (P<0.05). Cells transfected with pcNDA-HNF1B or pcNDA-PCDHA13 showed decreased levels of PI3K/AKT phosphorylation (P<0.05).
conclusionsOverexpression of HNF1B and PCDHA13 inhibits the phosphorylation of PI3K/AKT and hinders the malignant biological behavior of lung cancer A549 cells.
