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
The aim of the study is to investigate how lncRNA EWSAT1 regulates the tumorigenesis of non-small cell lung cancer (NSCLC) as a ceRNA by modulating miR-330-5p/ITGA5 axis. qRT-PCR was conducted to evaluate the expression of EWSAT1 in NSCLC tissue. Then, A549 cells were selected and divided into Blank shScramble, shEWSAT1, miR-330-5p inhibitor, shEWSAT1 + miR-330-5p inhibitor, and siITGA5 and miR-330-5p inhibitor + siITGA5 groups. Besides, a series of in-vitro experiments were carried out to determine the changes in cell proliferation, apoptosis, invasion, and migration in each group. In addition, xenograft models were also constructed on nude mice to detect the tumor volume and weight, and the expression of Ki67 and apoptosis in xenograft tumor were evaluated. In NSCLC tissue and cell, EWSAT1 was upregulated significantly, demonstrating a correlation with tumor diameter, differentiation, lymph node metastasis, and TNM stage. Dual luciferase reporter gene assay confirmed targeting relationships among miR-330-5p, EWSAT1, and ITGA5. In comparison with the Blank group, the number of cell clones in the shEWSAT1 group and siITGA5 decreased, with declined invasion and migration but increased apoptotic rate. Meanwhile, ITGA5, MMP-2, and MMP-9 were downregulated with upregulated cleaved caspase-3. However, the changes above were totally reversed in the miR-330-5p inhibitor group, and miR-330-5p inhibitor transfection abolished the effect of shEWSAT1. In addition, subcutaneous xenotransplantation showed that the tumor growth in shEWSAT1 group retarded significantly, with downregulation of Ki67 and increase apoptotic rate. Silencing EWSAT1 could inhibit the expression of ITGA5 via upregulating miR-330-5p, thus, resulting in the inhibition of NSCLC cell growth.
