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
backgroundNon-small cell lung carcinoma (NSCLC) is a primary prevalent type of cancer in people worldwide. Cisplatin (DDP) has been widely used to treat NSCLC; however, its curative effect was restrained under hypoxia. In this study, the effects of hypoxia treatment on DDP resistance and NSCLC progression and underneath mechanism were revealed.
methodsThe expression of circular RNA ASXL1 (circASXL1) and microRNA-206 (miR-206) in NSCLC tissues, cells and hypoxia-mediated NSCLC cells was determined by quantitative real-time polymerase chain reaction (qRT-PCR). The expression of proliferation, metastasis and apoptosis-related proteins, drug resistance-related protein and hypoxia-inducible factor-1alpha (HIF-1α) protein was detected by Western blot. The effects of circASXL1 knockdown on hypoxia-induced DDP resistance and NSCLC progression were revealed by cell counting kit-8 proliferation (CCK-8), cell colony formation, transwell and flow apoptosis assays. RNA immunoprecipitation (RIP) assay was performed to determine whether circASXL1 could form silence-inducing complexes with miRNA. The associated relationship between circASXL1 and miR-206 was predicted by circBank online database, and identified by RNA pull-down and dual-luciferase reporter assays. The effects between circASXL1 knockdown and miR-206 downregulation on tumor growth in vivo were investigated by in vivo tumor formation assay.
resultsCircASXL1 expression was dramatically upregulated, whereas miR-206 was significantly down-regulated in NSCLC tissues, cells and hypoxia-mediated NSCLC cells as compared to control groups. CircASXL1 knockdown reversed hypoxia-mediated promotion effects on DDP resistance, cell proliferation, migration, and invasion, and inhibition impact on cell apoptosis, whereas these effects were restored by miR-206 inhibitor. Additionally, circASXL1 was found to form silence-inducing complexes with miRNA and act as a sponge of miR-206. CircASXL1 silencing downregulated HIF-1α expression by controlling miR-206 expression. Furthermore, circASXL1 silencing repressed tumor growth in vivo by sponging miR-206.
conclusionCircASXL1 knockdown inhibited DDP resistance, cell proliferation, migration and invasion, whereas induced cell apoptosis under hypoxia by associating with miR-206 in NSCLC. This study provides a new sight in treating NSCLC with DDP under hypoxia.
