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
Impaired neural stem cell (NSC) proliferation/activation is associated with brain aging, but the underlying mechanisms remain poorly understood. Here, we unexpectedly find that DMTF1, a transcription factor that regulates the Arf/p53 axis in cancer, is down-regulated in the NSCs of a premature aging model driven by telomerase deficiency. DMTF1 up-regulation was able to rescue the impaired proliferation of telomere dysfunctional NSCs. Mechanistically, DMTF1 regulates the transcription of Arid2 and Ss18 genes, two subunits of the SWI/SNF complexes that mediate H3K27ac at E2F gene promoters to promote NSC proliferation. Accordingly, Arid2 or Ss18 depletion phenocopies DMTF1 loss in reducing H3K27ac levels, expression of E2F target genes, and NSC proliferation. Thus, our study has identified DMTF1 as a potential therapeutic target to reverse the proliferation defect of aged NSC that is modeled by telomere attrition and unearthed a distinct genetic program controlled by DMTF1 in NSC.
