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

We have recently shown that the expression of the FRAXE fragile site in Xq28 is associated with the expansion of a GCC trinucleotide repeat. In the families studied, FRAXE expression is also associated with mild mental handicap. Here we present data on families that previously had been diagnosed as having the fragile X syndrome but that later were found to be negative for trinucleotide repeat expansion at the FRAXA locus. In these families we demonstrate the presence of a GCC trinucleotide repeat expansion at the FRAXE locus. Studies of the FRAXE locus of normal individuals show that they have 6-25 copies of the repeat, whereas affected individuals have > 200 copies. As in the fragile X syndrome, the amplified CpG residues are methylated in affected males.
