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

Random X-chromosome inactivation is a hallmark of female mammalian somatic cells. This epigenetic mechanism, mediated by the long noncoding RNA Xist, occurs in the early embryo and is stably maintained throughout life, although inactivation is lost during primordial germ cell (PGC) development. Using a combination of single-cell allele-specific RNA sequencing and low-input chromatin profiling on developing mouse PGCs, we provide a detailed map of X-linked gene reactivation. Despite the absence of Xist expression, PGCs still harbor a fully silent X chromosome at embryonic day 9.5 (E9.5). Subsequently, X-linked genes undergo gradual and distinct regional reactivation. At E12.5, a substantial part of the inactive X chromosome resists reactivation, retaining an epigenetic memory of its silencing. Our findings define the orchestration of reactivation of the inactive X chromosome, a key event in female PGC reprogramming with direct implications for reproduction.
