Graphene-Based Electrochemical Sensors for the Determination of Pharmaceutical- and Agricultural-Based Emerging Contaminants in Water.
Article in Analytical chemistry, 2026. 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
Emerging contaminants (ECs), such as pharmaceuticals and agrochemicals, persist in aquatic systems and are often underestimated by targeted chromatographic methods that quantify only compounds with available analytical standards. Here, we present a portable electrochemical platform based on laser-induced graphene (LIG) and screen-printed graphene (SPG) electrodes, which couples hydrogen peroxide-assisted redox mediation with chronoamperometric detection to quantify the cumulative burden of oxidizable organic contaminants in water. Using amoxicillin (AMX) as a model compound, the system achieved sub-ppb sensitivity (LOD = 0.085 ppb) with excellent linearity (
