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

Characterisation of breakpoints in disease-associated balanced chromosome rearrangements (DBCRs), which disrupt or inactivate specific genes, has facilitated the molecular elucidation of a wide variety of genetic disorders. However, conventional methods for mapping chromosome breakpoints, such as in situ hybridisation with fluorescent dye-labelled bacterial artificial chromosome clones (BAC-FISH), are laborious, time consuming and often with insufficient resolution to unequivocally identify the disrupted gene. By combining DNA array hybridisation with chromosome sorting, the efficiency of breakpoint mapping has dramatically improved. However, this can only be applied when the physical properties of the derivative chromosomes allow them to be flow sorted. To characterise the breakpoints in all types of balanced chromosome rearrangements more efficiently and more accurately, we performed massively parallel sequencing using Illumina 1G analyser and ABI SOLiD systems to generate short sequencing reads from both ends of DNA fragments. We applied this method to four different DBCRs, including two reciprocal translocations and two inversions. By identifying read pairs spanning the breakpoints, we were able to map the breakpoints to a region of a few hundred base pairs that could be confirmed by subsequent PCR amplification and Sanger sequencing of the junction fragments. Our results show the feasibility of paired-end sequencing of systematic breakpoint mapping and gene finding in patients with disease-associated chromosome rearrangements.
