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
backgroundAlthough the prognosis of gastric cancer patients have a favorable progression, there are some patients with unusual patterns of locoregional and systemic recurrence. Therefore, a better understanding of early molecular events of the disease is needed. Current evidences demonstrate that long noncoding RNAs (lncRNAs) may be an important class of functional regulators involved in human gastric cancers development. Our previous studies suggest that HOTAIR contributes to gastric cancer development, and the overexpression of HOTAIR predicts a poor prognosis. In this study, we investigated the characteristic of the LncRNA FEZF1-AS1 in gastric cancer.
methodsQRT-PCR was used to detect the expression of FEZF1-AS1 in gastric cancer tissues and cells. MTT assays, clonogenic survival assays and nude mouse xenograft model were used to examine the tumorigenesis function of FEZF1-AS1 in vitro and in vivo. Bioinformatics analysis were used to select downstream target genes of FEZF1-AS1. Cell cycle analysis, ChIP, RIP,RNA Pulldown assays were examined to dissect molecular mechanisms.
resultsIn this study, we reported that FEZF1-AS1, a 2564 bp RNA, was overexpressed in gastric cancer, and upregulated FEZF1-AS1 expression indicated larger tumor size and higher clinical stage; additional higher expression of FEZF1-AS1 predicted poor prognosis. Further experiments revealed that knockdown FEZF1-AS1 significantly inhibited gastric cancer cells proliferation by inducing G1 arrest and apoptosis, whereas endogenous expression FEZF1-AS1 promoted cell growth. Additionally, RIP assay and RNA-pulldown assay evidenced that FEZF1-AS1 could epigenetically repress the expression of P21 via binding with LSD1, the first discovered demethylase. ChIP assays demonstrated that LSD1 could directly bind to the promoter of P21, inducing H3K4me2 demethylation.
conclusionIn summary, these data demonstrated that FEZF1-AS1 could act as an "oncogene" for gastric cancer partly through suppressing P21 expression; FEZF1-AS1 may be served as a candidate prognostic biomarker and target for new therapies of gastric cancer patients.
