Chromosome specific comparative genome hybridisation for determining the origin of intrachromosomal duplications.

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.
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
Chromosome specific comparative genome hybridisation (CGH) is a novel approach for the detection of cytogenetic abnormalities. It combines flow sorting of chromosomes, degenerate oligonucleotide primed (DOP)-PCR and a modified comparative genome hybridisation (CGH) technique to define the site and extent of intrachromosomal duplications. Chromosome specific paint probes for aberrant chromosomes and their normal homologues from four subjects with unbalanced duplications within chromosomes 2p11-15, 3q25-26, 5q34-qter, and 12q23-24.2 were made. They were then cohybridised on normal metaphase spreads and the ratio of their relative intensities of hybridisation analysed. The results were compared to those of similar experiments where regular CGH was performed on the same four patients. We provide evidence that this method can detect duplications and deficiencies which might be missed by conventional CGH, as the ratio of hybridisation of abnormal/normal DNA is 2:1 rather than 3:2. It is the method of choice where mosaicism is present or where only one of several homologous chromosomes is duplicated. Furthermore, it suggests that DOP-PCR amplifies all or most of the euchromatic regions of the genome equally.
