Efficient reidentification of chromosome slides from human metaphase spreads via microsatellite polymerase chain reaction.

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
In order to exclude inadvertent mixing of slides carrying metaphase spreads, chromosomal DNA was re-extracted several months after routine slide preparation (hypotonic treatment, spreading, fixation, staining, embedding and microscopic inspection) in different laboratories. The DNA yield was largely dependent on the number of cells originally fixed and the batch of the embedding material. Average fragment sizes ranged below 200 nucleotides. The polymerase chain reaction systems for DNA amplification included several polymorphic microsatellite loci specifically selected for short amplification products. Reidentification with a high probability for identity was possible by comparison with microsatellite alleles obtained from the peripheral blood of the individuals investigated. Possible applications, the differentiation potential and the limitations of the methodology are discussed.
