Selective extraction of low-abundance BRAF V600E mutation from plasma, urine, and sputum using ion-tagged oligonucleotides and magnetic ionic liquids.

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
Sequence-specific DNA extractions have the potential to improve the detection of low-abundance mutations from complex matrices, making them ideal for circulating tumor DNA analysis during the early stages of cancer. Ion-tagged oligonucleotides (ITOs) are oligonucleotides modified with an allylimidazolium salt via thiolene click chemistry. The allylimidazolium-based tag allows the ITO-DNA duplex to be selectively captured by a hydrophobic magnetic ionic liquid (MIL). In this study, the selectivity of the ITO-MIL method was examined by extracting low abundance of the BRAF V600E mutation-a common single-nucleotide polymorphism associated with several different cancers-from diluted human plasma, artificial urine, and diluted artificial sputum. Quantitative polymerase chain reaction (qPCR) was not able to distinguish a 9% BRAF V600E standard (50 fg·μL
