1 · What the graph read from it

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.

2 · The registry

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

Amperometric glucose biosensors remain indispensable analytical tools in clinical diagnostics due to their sensitivity, simplicity, and suitability for rapid measurements. Herein, an amperometric glucose biosensor based on immobilized glucose oxidase (GOx) and trimetallic nickel-platinum-palladium (NiPtPd) nanoparticles is reported. The NiPtPd nanoparticles deposited on a graphite rod electrode exhibited pronounced peroxidase-like activity and enabled efficient low-potential electrochemical transduction of the enzymatic reaction. The resulting biosensor displayed a linear response toward glucose in the concentration range from 0.04 to 1.58 mM. The limits of detection and quantification were determined to be 17.33 and 52.53 µM, respectively, and the sensitivity was 29.84 µA/mMcm
