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 inactivation has been hypothesised to play a role in the aetiology and clinical expression of the fragile X syndrome. The identification of the FMR1 gene involved in fragile X syndrome allows testing of the assumption that the fragile X locus is normally subject to X inactivation. We studied the expression of the FMR1 gene from inactive X chromosomes by reverse transcription of RNA followed by PCR (RT-PCR), both in somatic cell hybrids which retain an active or inactive human X chromosome and in a female patient with a large deletion surrounding the FMR1 gene. In both analyses, the data indicate that FMR1 is not normally expressed from the inactive X chromosome and is, therefore, subject to X chromosome inactivation. This finding is consistent with the results of previous studies of DNA methylation of FMR1 on active and inactive X chromosomes, verifies previous assumptions about the fragile X locus, and supports the involvement of X inactivation in the variable phenotype of females with full mutations of the FMR1 gene.
