The transcription factor Bcl11a is essential for B-1a cell maintenance during aging.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
B-1a cells, a self-renewing B cell subset essential for innate immunity, produce natural IgM antibodies that defend against pathogens, yet mechanisms sustaining their maintenance during aging remain unclear. We report that aging B-1a cells exhibit hallmarks of decline, including DNA damage, apoptosis, and reduced proliferation, with striking sex-specific disparities: aged females retain higher B-1a cell numbers than males, correlating with enhanced glycolysis and chromatin accessibility. Motif analysis of accessible regions identified the transcription factor Bcl11a, which shows elevated chromatin accessibility and expression in aged female B-1a cells but declines in males.
