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

The X chromosome is unique in the genome. In this review we discuss recent advances in our understanding of the genetics and epigenetics of the X chromosome. The X chromosome shares limited conservation with its ancestral homologue the Y chromosome and the resulting difference in X-chromosome dosage between males and females is largely compensated for by X-chromosome inactivation. The process of inactivation is initiated by the long non-coding RNA X-inactive specific transcript (XIST) and achieved through interaction with multiple synergistic silencing pathways. Identification of Xist-interacting proteins has given insight into these processes yet the cascade of events from initiation to maintenance have still to be resolved. In particular, the initiation of inactivation in humans has been challenging to study as: it occurs very early in development; most human embryonic stem cell lines already have an inactive X; and the process seems to differ from mouse. Another difference between human and mouse X inactivation is the larger number of human genes that escape silencing. In humans over 20% of X-linked genes continue to be expressed from the otherwise inactive X chromosome. We are only beginning to understand how such escape occurs but there is growing recognition that escapees contribute to sexually dimorphic traits. The unique biology and epigenetics of the X chromosome have often led to its exclusion from disease studies, yet the X constitutes 5% of the genome and is an important contributor to disease, often in a sex-specific manner.
