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
Long non-coding RNAs (lncRNAs) are a type of non-coding RNAs with transcript lengths exceeding 200 nt. lncRNAs suppress or promote cancer mainly by regulating gene expression. The aim of this study was to explore the role of lncRNAs activated in metastatic PCa (lncAMPC) in nasopharyngeal carcinoma (NPC). Total RNAs were isolated from NPC and adjacent non-tumor tissues from 60 NPC patients and subjected to RT-qPCR to analyze differential expression of lncAMPC and miR-214. The roles of lncAMPC and miR-214 in regulating PTEN expression were analyzed using RT-qPCR and Western blot. Cell proliferation was analyzed using the BrdU assay. The results showed that lncAMPC was overexpressed in NPC tissues and was localized in both nuclei and cytoplasms of NPC cells. MiR-214 was positively correlated with lncAMPC. LncAMPC overexpression upregulated miR-214 and indirectly downregulated PTEN via miR-214. BrdU incorporation assay showed that lncAMPC and miR-214 overexpression increased cell proliferation. PTEN overexpression completely reversed the promoting effects of lncAMPC and miR-214 overexpression on cell proliferation. Therefore, lncAMPC might downregulate PTEN via miR-214 to increase NPC cell proliferation.
