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

In male mammals, spermatogonial stem cells (SSCs) are essential for sustaining lifelong spermatogenesis within the testicular open niche, a unique environment that allows SSC migration over an extended niche area. As SSCs undergo continuous mitotic division, mutations accumulate and are transmitted to the descendant SSC clones. Therefore, SSC clonal fate behaviors, in terms of their efficiencies in completing spermatogenesis and undergoing expansion within the niche, influence sperm genomic diversity. We aimed to elucidate the effects of physiological aging on SSC clonal fate behavior within the testicular open niche. We used single-cell RNA sequencing, lineage tracing, and intravital live imaging to investigate SSC behavior in aged mouse testes, where spermatogenesis, although reduced, persists. We found that undifferentiated spermatogonia maintained gene expression heterogeneity during aging. Among these, GFRα1
