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
Heart failure (HF) is the leading cause of death in patients with maintenance hemodialysis (MHD). Biomarkers has an important guiding role in the early diagnosis, risk stratification, and prognostic assessment of HF. Increasing studies have indicated that long non-coding RNAs (lncRNAs) have played an indispensable role in the regulatory network of HF. This study was aiming to explore the expression profiles of lncRNAs in patients treated with MHD developing heart failure. Peripheral blood mononuclear cells were isolated from 4 hemodialysis patients with reduced ejection fraction (HFrEF) and 4 hemodialysis patients with preserved ejection fraction (HFpEF), respectively. The expression profile analysis of lncRNAs was performed by using Illumina Novaseq 6000 sequencer. Quantitative real time polymerase chain reaction (qRT-PCR) was used to verify the expression of representative differentially expressed lncRNAs. Based on lncRNA-miRNA-mRNA-KEGG network analysis, the potential role of candidate lncRNAs and their association with the severity of HF were further evaluated. In total, 1,429 differentially expressed lncRNAs were found between patients with HFrEF and patients with HFpEF, of which 613 were up-regulated and 816 were down-regulated (P < 0.05). Five candidate lncRNAs were screened out by a series of bioinformatic analyses. After being compared with miRBase, ENST00000561762, one of the 5 candidates, was considered the most likely lncRNA to be serving as a precursor for miRNA. Nine predicted target genes were found by further lncRNA-miRNA-mRNA-KEGG network analysis, and among which ITGB5 was enriched in the actin dynamics signaling pathway. In another cohort of hemodialysis patients, the expression of lncRNA ENST00000561762 was verified by qRT-PCR. Further analysis revealed that there was a strong correlation between left ventricular ejection fraction and ENST00000561762, proBNP, and 6-minute walk distance, respectively. LncRNAs expression profile was remarkably different in hemodialysis patients with HFrEF compared to those with HFpEF. Among which, lncRNA ENST00000561762 was considered as a promising biomarker for patients with HFrEF as it was predicted to be a miRNA precursor to regulate the actin dynamics signaling pathway.
