Article in Cancer management and research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 4 papers.
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
backgroundThe incidence of cholangiocarcinoma (CCA) is on the rise in recent years, and its pathogenesis may be associated with the deregulation of circular RNAs (circRNAs). Hence, we aimed to investigate the role of circRNA homeodomain interacting protein kinase 3 (circ_HIPK3) in CCA.
methodsThe expression of circ_HIPK3, miR-148a-3p and unc-51 like kinase 3 (ULK1) mRNA was detected using quantitative real-time polymerase chain reaction (qPCR). The role of circ_HIPK3 in cell proliferation was detected by 3-[4, 5-dimethylthiazol-2-yl]-2, 5 diphenyl tetrazolium bromide (MTT) assay and colony formation assay. Cell apoptosis and cell cycle progression were investigated using flow cytometry assay. Cell migration and invasion were detected by transwell assay. The protein levels of ULK1 and migration/invasion-associated markers were measured using Western blot. The putative relationship between miR-148a-3p and circ_HIPK3 or ULK1 was validated by dual-luciferase reporter assay. The role of circ_HIPK3 was also investigated in vivo.
resultsCirc_HIPK3 was overexpressed in CCA tissues and cells. In function, circ_HIPK3 knockdown inhibited CCA cell proliferation, migration and invasion and induced apoptosis and cycle arrest. It was confirmed that miR-148a-3p was a target of circ_HIPK3, and ULK1 was a target of miR-148a-3p. Circ_HIPK3 regulated ULK1 expression by targeting miR-148a-3p. Rescue experiments showed that miR-148a-3p inhibition reversed the effects of circ_HIPK3 knockdown. Besides, miR-148a-3p enrichment-blocked cell proliferation, migration and invasion were recovered by ULK1 overexpression. In vivo, circ_HIPK3 knockdown inhibited solid tumor growth.
conclusionCirc_HIPK3 knockdown blocked CCA malignant development partly via regulating the miR-148a-3p/ULK1 pathway.
