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

Early detection of aflatoxins is crucial to safeguard food safety. In this study, a new azobenzene monomer was synthesized and its photo-isomerization behavior in methanol and dimethyl sulfoxide was studied. A photo-switchable molecularly imprinted polymer (PMIP) designed for selectively recognizing aflatoxin B1 (AFB1) was fabricated via a surface imprinting technique. A dummy template, 5,7-dimethoxycoumarin was incorporated during the polymerization process. The photo-responsive behaviors of candidate monomers were systematically evaluated in methanol and dimethyl sulfoxide. The resulting PMIP was used as an extraction adsorbent for pretreatment prior to high-performance liquid chromatography-mass spectrometry analysis with its adsorption capacity could be controlled by light irradiation (365 nm and 440 nm). The method demonstrated a linear calibration interval from 50 to 1000 ng·mL⁻¹ with detection limit of 5.1 ng·mL⁻¹, and exhibited favorable binding capacity values between 90.8% and 95.4% when used for the determination of AFB1 in corn, reflecting the strong recognition affinity of PMIP toward AFB1.
