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
backgroundLong non-coding RNA (lncRNA) plays a vital role in the occurrence and development of varieties of tumors. Previous studies have shown that lncRNA GClnc1 is highly expressed in osteosarcoma (OS). However, the mechanism of lncRNA GClnc1 in osteosarcoma has not been fully elucidated. In this study, we investigated the biological roles of lncRNA GClnc1 in osteosarcoma and unveiled its underlying mechanisms.
methodsThe expression of lncRNA GClnc1 in OS cells was detected by real-time quantitative PCR (qRT-PCR). The functional roles of lncRNA GClnc1 were examined by CCK8, trans-well, scratch wound healing assay, colony formation, and apoptosis assays in osteosarcoma cells upon silencing or overexpressing GClnc1. Western blot analysis, qRT-PCR, and RNA co-immunoprecipitation (RIP) assays were used to detect the interaction between lncRNA GClnc1 and NONO.
resultsThe expression of lncRNA GClnc1 was up-regulated in osteosarcoma cell lines. Knockdown of lncRNA GClnc1 suppressed the cell growth, migration, and invasion of OS cells, whereas the over-expression of GClnc1 improved the proliferation, migration, and invasion of OS cells. Mechanistically, we identified that lncRNA GClnc1 regulates the stability of NONO by blocking FBXW7-mediated ubiquitination degradation. Additionally, overexpression of NONO can reverse GClnc1 silencing exerted suppression of the cell proliferation, migration, and invasion, and vice versa.
conclusionsOur study elucidated that lncRNA GClnc1 participates in the progression of OS by regulating the NONO signal pathway. Targeting GClnc1 provides a potential target for future clinical treatment of OS.
