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
backgroundGiven antisense long noncoding RNAs (lncRNAs) poly C binding protein-1 antisense RNA1 (PCBP1-AS1) was significantly co-expressed with tumor necrosis factor receptor associated factor 5 (TRAF5) mRNA in vulvar squamous cell carcinoma (VSCC). TRAF5 could mediate nuclear factor kappa B (NF-κB) activation and regulate biological behaviors of tumor cells. Herein, we determined whether PCBP1-AS1 could affect the tumor behaviors of VSCC by regulating TRAF5 and NF-κB expression.
methodsThe expression of PCBP1-AS1 and TRAF5 mRNA in VSCC tissues and cells was detected via quantitative real-time polymerase chain reaction, while the protein expression levels of TRAF5, p65, p-p65, c-Rel, and IκBα were examined by immunoblotting. After the overexpression of PCBP1-AS1 and RNA interference knockdown of TRAF5 in SW954 cells, NF-κB activation-nuclear translocation fluorescence, the CCK-8 assay, Annexin V-FITC & PI fluorescent staining, the wound healing assay, and the Transwell invasion assay were performed to evaluate the activity of NF-κB, cellular proliferation, apoptosis, migration, and invasion.
resultsPCBP1-AS1 and TRAF5 mRNA expression were downregulated in VSCC tissues and were correlated with patient clinicopathological characteristics. The protein expression of TRAF5, p65, p-p65, c-Rel, and IκBα protein in VSCC tissues was significantly decreased. We demonstrated that PCBP1-AS1 positively regulated the expression of TRAF5. PCBP1-AS1 overexpression or knockdown of TRAF5 regulated the activity of the NF-κB pathway. Increase of PCBP1-AS1 significantly inhibited proliferation and enhanced apoptosis via TRAF5-mediated regulation of the NF-κB signaling pathway. Additionally, PCBP1-AS1 can suppress migration and invasion in an NF-κB-independent manner.
conclusionsAs a tumor suppressor gene, PCBP1-AS1 regulates the proliferation and apoptosis of VSCC via TRAF5-mediated expression of the NF-κB.
