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

X-chromosome dosage compensation in female placental mammals is achieved by X-chromosome inactivation (XCI). Human pre-implantation embryos are an exception, in which dosage compensation occurs by X-chromosome dampening (XCD). Here, we examined whether XCD extends to human prenatal germ cells given their similarities to naive pluripotent cells. We found that female human primordial germ cells (hPGCs) display reduced X-linked gene expression before entering meiosis. Moreover, in hPGCs, both X chromosomes are active and express the long non-coding RNAs X active coating transcript (XACT) and X inactive specific transcript (XIST)-the master regulator of XCI-which are silenced after entry into meiosis. We find that XACT is a hPGC marker, describe XCD associated with XIST expression in hPGCs and suggest that XCD evolved in humans to regulate X-linked genes in pre-implantation embryos and PGCs. Furthermore, we found a unique mechanism of X-chromosome regulation in human primordial oocytes. Therefore, future studies of human germline development must consider the sexually dimorphic X-chromosome dosage compensation mechanisms in the prenatal germline.
