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
objectiveNasopharyngeal carcinoma (NPC) is a malignant tumor of the head and neck. Distant metastasis and drug resistance are the main causes of cancer-related death. A better understanding of the molecular mechanisms that affect the progression of NPC would contribute to clinical treatment. This paper aims to investigate the effects of the long noncoding RNA (lncRNA) small nucleolar RNA host gene 1 (SNHG1) on biological phenotypes of NPC cells and its related mechanisms.
methodsThe expression of SNHG1 and miR-424-5p in non-cancerous nasopharyngeal mucosa tissues and NPC tissues, as well as in normal nasopharyngeal epithelial cells and NPC cells was detected by qRT-PCR. HK1 and C666-1 cells were transfected with SNHG1 overexpression vector (OE-SNHG1), miR-424-5p mimic, SNHG1 knockdown vector (sh-SNHG1), or miR-424-5p inhibitor, followed by detection of transfection efficiency by qRT-PCR, cell viability by MTT, and invasive and migratory abilities by transwell invasion assay and cell scratch test. Moreover, the relationship between SNHG1 and miR-424-5p was detected by dual-luciferase reporter and RIP assays.
resultsIn NPC tissues and cells, SNHG1 was upregulated but miR-424-5p was downregulated. Transfection with OE-SNHG1 or miR-424-5p inhibitor promoted proliferative, invasive, and migratory phenotypes of HK1 and C666-1 cells; transfection of sh-SNHG1 or mi-miR-424-5p induced reverse trends. Mechanistically, SNHG1 negatively regulated miR-424-5p expression, and transfection of miR-424-5p inhibitor counteracted the inhibitory effects of sh-SNHG1 on the proliferative, invasive, and migratory phenotypes of HK1 and C666-1 cells.
conclusionLncRNA SNHG1 promoted proliferation, invasion and migration of NPC cells by repressing miR-424-5p expression.
