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
Objective: Hypertension significantly contributes to morbidity and mortality. Nuclear receptor subfamily 4 group a member 1 (Nur77) participates in regulating oxidative stress, but the mechanism in hypertension remains unclear. This study aimed to explore the function of Nur77 in oxidative stress induced by Angiotensin II (Ang II) in vascular smooth muscle cells (VSMCs) in hypertension. Material and Methods: First, models of VSMC with Nur77, nucleotide-binding oligomerization domain-like receptor family caspase recruitment domain containing 3 (NLRC3) and tumor necrosis factor receptor-associated factor 6 (TRAF6) knockdown or overexpression were constructed using Short Hairpin RNA (Nur77) or pcDNA3.1 vector, respectively. Next, the putative-binding motifs between Nur77 and NLRC3 promoters were detected by dual luciferase assay. We conducted reverse transcription quantitative polymerase chain reaction (qPCR) and Western blot (WB) analysis to detect Nur77, NLRC3, and TRAF6 levels in VSMCs. Then, cell counting kit-8 assay, 5-ethynyl-2'-deoxyuridine assay, wound-healing assay, enzyme-linked immunosorbent assay, and 2',7'-dichlorofluorescin diacetate were employed to examine the impact of the knockdown or overexpression of Nur77, NLRC3, and TRAF6 on VSMCs treated with Ang II. The assays measured cell viability and proliferation, cell migration, malondialdehyde levels, and reactive oxygen species levels. Results: The overexpression of Nur77 repressed cell growth ( Conclusion: Nur77 suppressed growth and oxidative stress induced by Ang II in VSMCs by promoting NLRC3 transcription, which, further, repressed the TRAF6/NF-κB axis. This understanding provides novel insights into the pathogenesis of hypertension.
