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

Remarkable interest in the epigenetic status of human induced pluripotent stem (iPS) cells inspired numerous studies of their X-inactivation patterns. However, both the presence and the absence of X-inactivation have been described to date in undifferentiated iPS cells. The reasons for the discordant results between different studies are unclear, and further X-inactivation testing is warranted for all female human iPS cell lines. Some of the inconsistency in the current data most likely results from the use of different X-inactivation assays by different authors. We provide a detailed protocol for a simple, reliable and affordable X-inactivation assay based on promoter methylation and CAG-repeat polymorphism in the human androgen receptor (AR) gene at Xq11.2. This assay is commonly used in clinical genetic laboratories and we propose that it could be ideal for routine assessment and monitoring of the X-inactivation status in female human iPS cell lines.
