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
introductionThe present study evaluated the effects of the long non-coding RNA (lncRNA) gastric carcinoma high-expressed transcript (GHET1) in cervical carcinoma development.
methodsThe expression levels of GHET1 and PTEN were measured using in situ hybridisation, immunohistochemistry (IHC) and quantitative reverse transcription PCR assay to investigate their correlations. In an in vitro study, the effects of GHET1 knockdown on the biological activities of SiHa and HeLa cells were evaluated by MTT, flow cytometry, transwell and wound-healing assays and relative protein expression was measured using western blotting. In an in vivo experiment, cell apoptosis and relative protein expression were measured in nude mice using TUNEL and IHC assays, respectively.
resultsThe expression levels of lncRNA GHET1 and PTEN protein differed significantly between cancer and adjacent normal tissues (P< 0.05) and were negatively correlated in the clinical data. In vitro, proliferation rateswere significantly down-regulated in SiHa and HeLa cells. The GHET1 knockdown (si-GHET1) groups showed significantly higher G1 phase and apoptosis rates and significantly suppressed invasion and migration abilities compared with the normal control (NC) group (P< 0.05 for all). The expression levels of PTEN, PI3 K, AKT, P53, matrix metalloproteinase (MMP)-2 and MMP-9 proteins differed significantly between the si-GHET1 and NC groups (P< 0.05 for all). In vitro, the lncRNA group showed significantly suppressed tumour volume and weight, increased cell apoptosis and different relative protein expression levels compared with the NC group (P< 0.05 for all).
conclusionGHET1 knockdown suppressed cervical carcinoma development via the PTEN/PI3 K/AKT signalling pathway.
