Flexible Gold-Based Electrochemical Biosensor for Highly Sensitive Detection of Saxitoxin in Water Samples.

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
Saxitoxin (STX) is a highly potent cyanobacterial toxin, posing serious risks to aquatic ecosystems and human health. Conventional methods for STX detection, such as high-performance liquid chromatography (HPLC), mass spectrometry (MS), and enzyme-linked immunosorbent assays (ELISA), are effective but costly, labor-intensive, and nonportable, motivating alternative strategies. Here, we report a flexible electrochemical biosensor fabricated via photolithography of gold electrodes on affordable polymer-based substrates for STX detection in water samples. The electrodes showed high mechanical stability, low charge transfer resistance, and an electroactive surface area 55% larger than the geometric area. Anti-STX antibodies were immobilized using a simple sodium citrate-assisted physisorption method. The biosensor response, monitored by cyclic voltammetry in phosphate-buffered solution with [Fe-(CN)
