A mechanistic study of the electron capture dissociation of oligonucleotides.
Article in Journal of the American Society for Mass Spectrometry, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Electron capture dissociation (ECD) of a series of custom-synthesized oligonucleotide pentamers was performed in a Fourier-transform mass spectrometer with a conventional filament-type electron gun. Dissociation of oligonucleotide ions by electron capture generates primarily w/d-type and z/a-type ions with and without the loss of a nucleobase fragment ions. Minor yields of radical [z/a + H]. fragment ions were also observed in many cases. It is interesting to note that some nucleoside-like fragment ions and protonated nucleobase ions (except thymine-related nucleobases and nucleoside-like fragments) were observed in most ECD spectra. The formation of these low-mass fragment ions was tentatively attributed to the secondary fragmentation of the radical [z + H]. fragment ions. From the ECD tandem mass spectra of a series of C/T based binary oligonucleotide ions, including d(CTCTC), d(CTTTC), d(TCCCT), d(CCCCT), and d(TCCCC), it was clearly demonstrated that the formation of many sequence ions was sensitive to the position of cytosine (or the position of charge carrier). The findings of this work support a notion that the ECD of protonated oligonucleotide molecules is charge-directed with the electron being captured by the protonated nucleobase.
