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

DNA methylation and hydroxymethylation patterns at the 5th carbon of cytosine (5mC and 5hmC) in CpG dinucleotides tightly regulate gene transcription in normal physiology, aging, and associated diseases, including ischemic stroke. Resilience to ischemic brain injury depends on the interplay of diverse neural and non-neural cell types, whose gene expression and identity are predominantly regulated by brain-enriched epigenetic mechanisms, particularly the dynamics of 5mC and 5hmC in response to changing transcriptional demands under ischemic stress. In this review, we discussed the role of 5mC and 5hmC in aging and the pathophysiology of stroke. Given the high degree of inter-individual variability in stroke studies and its multifactorial etiology, we emphasize the need for personalized, temporally controlled, epigenome-based therapies to improve stroke outcomes.
