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
An abdominal aortic aneurysm (AAA) is a life-threatening vascular condition characterized by the dilation of the abdominal aorta, with ferroptosis playing a significant role in its pathogenesis. This study investigates the therapeutic potential of engineering biomimetic nanovesicles to deliver phosphatidylethanolamine-binding protein 1 (PEBP1) mRNA for inhibiting ferroptosis in vascular smooth muscle cells (VSMCs) and preventing AAA progression. Differential gene expression analysis of the AAA transcriptomic dataset GSE57691 identified 243 differentially expressed genes (DEGs), intersecting with 12 ferroptosis-related genes. Single-cell analysis of dataset GSE237230 highlighted PEBP1 as a key gene in VSMCs. Overexpression of PEBP1 in VSMCs enhanced proliferation, reduced reactive oxygen species (ROS) and iron levels, and inhibited apoptosis and ferroptosis via the NRF2/GPX4 axis. The engineered biomimetic nanovesicles demonstrated significant uptake by VSMCs and effective delivery of PEBP1 mRNA. In vivo studies confirmed that these nanovesicles substantially inhibited AAA progression in mice. This study presents a novel bioengineering approach for AAA treatment by targeting ferroptosis through PEBP1 mRNA delivery, offering a promising molecular strategy for the prevention and management of AAA.
