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
High aerobic glycolysis in retinal photoreceptors, as in cancer cells, is implicated in mitigating energy and metabolic demands. Lactate, a product of glycolysis, can exert epigenetic regulation through histone lactylation in cancer. Here, we show that enhanced ATP production during mouse retinal development is achieved primarily through increase in glycolysis. Histone lactylation, especially H3K18La, parallels increased glycolysis and lactate levels in the developing retina. Multi-omics analyses, combined with confocal imaging, reveal the localization of H3K18La near H3K27Ac in the euchromatin at promoters of active retinal genes. In mouse retinal explants, glucose metabolism is associated with lactate levels as well as H3K18La and consequently gene expression. However, inhibition of glycolysis with 2-deoxyglucose (2-DG) reduces global H3K18La and H3K27Ac marks with somewhat distinct transcriptional changes. Evaluation of accessible chromatin at H3K18La-marked promoters uncovers an enrichment of GC-rich motifs for transcription factors of SP, KMT and KLF families, among others, indicating the specificity of H3K18La-mediated gene regulation. Our results indicate glycolysis/lactate/H3K18La as a potential axis for transcriptional response to changing metabolic conditions in the retina, especially photoreceptors.
