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

purposeTo develop a single-tube polymerase chain reaction (PCR) panel of highly polymorphic markers for preimplantation genetic diagnosis (PGD) of fragile X syndrome (FXS).

methodsAn in silico search was performed to identify all markers within 1 Mb flanking the FMR1 gene. Selected markers were optimized into a single-tube PCR panel and their polymorphism indices were determined from 272 female samples from three populations. The single-tube assay was also validated on 30 single cells to evaluate its applicability to FXS PGD.

resultsThirteen markers with potentially high polymorphism information content (PIC) and heterozygosity values were selected and optimized into a single-tube PCR panel together with AMELX/Y for gender determination. Analysis of 272 female samples confirmed the high polymorphism (PIC > 0.5) of most markers, with expected and observed heterozygosities ranging from 0.31 to 0.87. More than 99% of individuals were heterozygous for at least three markers, with 95.8% of individuals heterozygous for at least two markers on either side of the FMR1 CGG repeat.

conclusionThe tetradecaplex marker assay can be performed directly on single cells or after whole-genome amplification, thus supporting its use in FXS PGD either as a standalone linkage-based assay or as a complement to FMR1 mutation detection.Genet Med 18 9, 869-875.
