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
objectiveTo investigate the effect of long non-coding RNA (LncRNA) differentiation antagonizing non-protein coding RNA (DANCR) on the immune microenvironment of glioma cells by regulating the miR-656/bone morphogenetic protein receptor type 1A (BMPR1A) axis.
methodsThe expression levels of DANCR, miR-656 and BMPR1A in glioma cells were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The U87 cells were transfected or co-transfected to form the following groups: sh-DANCR (transfected with sh-DANCR), overexpression (pcDNA 3.1) DANCR (transfected with pcDNA 3.1 DANCR), NC sh (transfected with negative control sh), pcDNA 3.1 (transfected with pcDNA 3.1 vector), sh-DANCR + miR-656 inhibitor (co-transfected with sh-DANCR and miR-656 inhibitor), sh-DANCR + NC inhibitor (co-transfected with sh-DANCR and NC inhibitor), sh-DANCR + pcDNA 3.1 BMPR1A (co-transfected with sh-DANCR and pcDNA 3.1 BMPR1A), and sh-DANCR + pcDNA 3.1 (co-transfected with sh-DANCR and pcDNA 3.1 BMPR1A). The untreated U87 cells were used as the blank group. The proliferation of U87 cells was detected by CCK-8; invasion and migration were detected by Transwell assay; apoptosis was detected by flow cytometry; the expression of DANCR, miR-656, and BMPR1A mRNA in cells was detected by qRT-PCR; the targeting relationship between DANCR and miR-656 was verified by dual-luciferase; and BMPR1A and immune escape factors [programmed death receptor 1 (PD-1) and programmed death-ligand 1 (PD-L1)] were detected by Western blot.
resultsThe mRNA expressions of DANCR and BMPR1A in U87, A172, LN229 and U251 cells were significantly increased, while the expression of miR-656 was significantly decreased compared with those in NHA cells (
conclusionLncRNA DANCR improves the immune microenvironment of glioma cells and inhibits the malignant behavior development of cancer cells by regulating the miR-656/BMPR1A axis.
