Epicatechin Protects Against Post-Cardiac Arrest Brain Injury in Aged Rats via NRG1-Mediated Suppression of Neuroinflammation.
Article in Current issues in molecular biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Chronic inflammation conducts an irreplaceable role in the aging process. More importantly, the impact is particularly significant in scenarios involving cardiac arrest and cardiopulmonary resuscitation (CA/CPR), where elderly individuals are inclined to suffer from more severe inflammatory injuries when compared to younger counterparts. Network pharmacology demonstrated a tight correlation between epicatechin (EC), aging, and the NRG1-NF-κB signaling pathway. With an aim to investigate whether EC suppressing inflammatory aging and alleviating post-CA/CPR brain injury is associated with the inhibition of the NRG1-NF-κB pathway, we established a model of naturally aged 21-month-old rats subjected to CA/CPR. A network pharmacology method was employed to pinpoint possible pathways that connect EC to neuroinflammation associated with aging. Sixty rats were randomly divided into three groups for feeding: a control group (pure water) and EC groups (EC was administered by gavage at doses of 1 mg/kg and 2 mg/kg respectively from the 12th month). Those groups underwent a CA/CPR procedure. At 24-h post-resuscitation, neurological scores, cortical pathology staining and assessments of neural injury were conducted. Expression levels of NRG1-NF-κB pathway-relevant inflammatory factors and proteins underwent systematic investigation by carrying out ELISA, RT-PCR, and Western blotting. In comparison with the 21-month-old groups treated with water, the 21-month-old groups treated with EC at 1 mg/kg and 2 mg/kg demonstrated decreased
