The method of single-nucleotide variations detection using capillary electrophoresis and molecular beacons.
Article in Molecular biology reports, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
We demonstrate that single-nucleotide variations in a DNA sequence can be detected using capillary electrophoresis (CE) and molecular beacons (MBs). In this method, the region surrounding the site of a nucleotide variation was amplified in a polymerase chain reaction, then hybridize PCR products with each of MBs. The sequences of the PCR products are different at the site of 2,044 in exon of interleukin (IL)-13 which to be identified. Through denaturation, the PCR product became single strand and hybridized with the completely complementary MB. The MB-target duplexes were separated using CE and solution-based fluorescence techniques. The results show that in each reaction a fluorescent response was elicited from the molecular beacon which was perfectly complementary to the amplified DNA, but not from the other MB whose probe sequence mismatched the target sequence. The method of CE based on MBs is able to identify single-nucleotide variations in a DNA sequence and can discriminate the genotyping of the SNP between the homo- and heteroduplexes of DNA fragments.
