G-Quadruplex Structure in the ATP-Binding DNA Aptamer Strongly Modulates Ligand Binding Activity.
Article in ACS omega, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Secondary structures formed by single-stranded DNA aptamers can allow for the binding of small-molecule ligands. Some of these secondary structures are highly stable in solution and are great candidates for use in the development of molecular tools for biomarker detection, environmental monitoring, and others. In this paper, we explored adenosine triphosphate (ATP)-binding aptamers for the simultaneous detection of two small-molecule ligands: adenosine triphosphate (ATP) and thioflavin T (ThT). The aptamer can form a G-quadruplex (G4) structure with two G-quartets, and our results show that each of these quartets is equally involved in binding. Using fluorescently labeled and label-free methods, we further explored the role of the G4 motif in modulating the ligand binding property of the aptamer by making two extended variants that can form three or four G-quartet G4 structures. Through equilibrium binding and electrospray ionization mass spectrometry (ESI-MS) analysis, we observed a stronger affinity of aptamers to ATP by the variant G4 constructs relative to the native aptamer (
