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

A colorimetric/fluorescent dual-mode sensor has been developed based on well-dispersed PtMn alloy/porous N-doped carbon nanoflowers (PtMn/CNFs), which have bifunctional ascorbate oxidase (AAO) and peroxidase (POD)-like activities. Specifically, the POD-like activity of PtMn/CNFs enables colorimetric ascorbic acid (AA) detection by oxidizing 3,3',5,5'-tetramethylbenzidine (TMB) to a blue product, while the AAO-like activity facilitates fluorescent detection of AA by catalyzing its oxidation to dehydroascorbic acid (DHA), which subsequently reacts with o-phenylenediamine (OPD) to generate a fluorescent product. The sensor demonstrates wide linear ranges of 2 to 250 µM (detection limit: 0.218 µM) and 2.5-500 µM (detection limit: 0.101 µM) for colorimetric and fluorescent AA detection, respectively. This was successfully applied to AA detection in juice beverages and showed high accuracy with satisfying results. This work offers a simple, reliable, and efficient strategy for monitoring food quality.
