Rational design of sequestered DNAzyme beacons to enable flexible control of catalytic activities.
Article in RSC advances, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
DNAzymes as functional units play increasingly important roles for DNA nanotechnology, and fine control of the catalytic activities of DNAzymes is a crucial element in the design and construction of functional and dynamic devices. So far, attempts to control cleavage kinetics can be mainly achieved through varying the concentrations of the specific metal ions. Here we present a facile sequestered DNAzyme beacon strategy based on precisely blocking the catalytic core of the DNAzyme, which can flexibly regulate the DNAzyme cleavage kinetics without changing the concentrations of metal ions. This strategy can be extended to couple with a large number of other RNA-cleaving DNAzymes and was successfully applied in designing a dual stem-loop structure probe for arbitrary sequence biosensing, which provides the possibility of scaling up versatile and dynamic DNA devices that use DNAzymes as functional modules.
