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 XX female mammals, one of the two X chromosomes is epigenetically inactivated to equalize gene expression with XY males. The formation of the inactive X chromosome (Xi) is regulated by an X-linked long noncoding RNA Xist, which accumulates on the entire length of the chromosome in cis and induces heterochromatin formation. However, the mechanism by which Xist RNA "paints" the Xi has long remained elusive. Here, we show that a matrix protein hnRNP U/SP120/SAF-A is required for the accumulation of Xist RNA on the Xi. Xist RNA and hnRNP U interact and upon depletion of hnRNP U, Xist RNA is detached from the Xi and diffusely localized into the nucleoplasm. In addition, ES cells lacking hnRNP U expression fail to form the Xi. We propose that the association with matrix proteins is an essential step in the epigenetic regulation of gene expression by Xist RNA.
