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
Developing nano-iontronic devices that minimize ionic interference is essential for precise measurements in complex physiological systems. Graphdiyne (GDY), a novel carbon allotrope featuring sub-nanometer pores, enables effective regulation of ionic transport and is therefore a promising material for high-performance iontronic applications. Here, we report a pH-responsive nano-iontronic device fabricated by stacking and overlapping graphdiyne (so-GDY) layers onto the tip of the nanopipette. This so-GDY-based pH nano-iontronic sensor exhibits a linear decrease in ionic current under negative potential as the pH decreases from 8.00 to 5.50. This response is attributed to protonation of the oxygen-containing functional groups on the so-GDY surface and edges, which diminishes the negative surface charge and thereby reduces ionic conductivity. A key advantage of this nano-iontronic device is its excellent selectivity, demonstrating robust resistance to interference from divalent cations (Mg
