1 · What the graph read from it

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.

2 · The registry

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

backgroundThe role of ferroptosis in Cardiac arrest (CA)-induced cerebral edema remains unclear. PURPOSE: To investigate whether ferroptosis contributes to blood-brain barrier (BBB) disruption and aquaporin-4 (AQP4) dysfunction following CA. STUDY TYPE: Prospective. ANIMAL MODEL: Asphyxia-induced CA rat model. Forty two rats were used and assigned to the CA (24) and the sham (18) group. FIELD STRENGTH/SEQUENCE: T2-weighted anatomical imaging with 2D turbo spin-echo sequence, QSM with 3D GRE sequence, IVIM with 2D RESOLVE EPI sequence, ASSESSMENT: Multiparametric MRI was performed 24 h after return of spontaneous circulation (ROSC). Imaging findings were validated using histology, immunohistochemistry, Western blot, and transmission electron microscopy. STATISTICAL TESTS: Unpaired two-tailed Student's T-test was used. A p value less than 0.05 was considered statistically significant.

resultsCA led to marked neurological deficits, although no obvious abnormalities were observed on T DATA

conclusionThis study provides evidence for a sequential cascade after CA and ROSC in which iron overload is associated with ferroptosis, which is linked to disruption of the blood-brain barrier. This barrier disruption coincides with AQP4 depolarization, inducing cytotoxic and vasogenic edema, which, along with depolarization, is accompanied by neuronal death. Multimodal MRI noninvasively captures this process, offering an early detection and monitoring platform for ferroptosis-related brain injury and underscoring its potential as a translational tool for neuroprotective interventions. EVIDENCE LEVEL: 1. TECHNICAL EFFICACY: Stage 1.
