Approaching to Calibration-Free Ion Detection Based on Thin Layer Coulometry with Ultrathin Ion-Selective Membranes.
Article in ACS measurement science au, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
In pursuit of calibration-free all-solid-state ion-selective electrodes (ISEs), we propose a coulometry strategy based on thin-layer samples confined adjacent to the ion-selective membrane (ISM) surface, with the system being controlled under a cathodic potential sweep. The ion-to-electron transducer in the ISE is the conducting polymer poly(3-octylthiophene) (POT), the oxidation state of which changes upon the application of a cathodic sweep and triggers the accumulation of the preferred cation in the ISM. This accumulation is provided of absolute nature (i.e., the cation concentration is totally depleted in the sample) when the capacity of the membrane encompasses the charge of the cation of interest in the sample (K
