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 novel dual-channel core-shell-shell up-conversion nanoparticle-based fluorescence immunochromatographic assay (CSS-UCNPs-dICA) combined with multiple-impurity adsorption purification (MIA) pretreatment was designed for the simultaneous and rapid detection of aflatoxin B1 (AFB1) and fumonisin B1 (FB1) in pet food. Capitalizing on the superior luminescent properties of the CSS-UCNPs, the assay exhibited high sensitivity with limits of detection (LODs) of 0.025 ng/mL for AFB1 and 0.25 ng/mL for FB1. This represents a 20-fold sensitivity enhancement compared to colloidal gold-based immunochromatography. In spiking experiments, the assay achieved recoveries ranging from 97.69% − 104.66% for AFB1 and 97.68%–105.26% for FB1 in pet food samples. The generated results were consistent with data from liquid chromatography-tandem mass spectrometry (LC-MS/MS) analyses of naturally contaminated pet foods, confirming the superior practicality, rapidness, and simplicity. Thus, the developed CSS-UCNPs-dICA strip is a promising tool for the rapid, on-site, and large-scale screening of AFB1 and FB1 co-contamination in pet food.
