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

Ratiometric photoelectrochemical (PEC) sensors have emerged as a compelling class of analytical tools, offering internal calibration, enhanced signal stability, and improved tolerance to environmental variability. These advantages are particularly relevant to the field of food analysis, where sample complexity often compromises the reliability of single-signal detection strategies. In recent years, diverse ratiometric PEC platforms have been developed. This review systematically categorizes ratiometric PEC sensors into five main types: wavelength-resolved, voltage-resolved, spatially resolved, dual-mode, and other emerging strategies involving polarity switching or stimulus-responsive interfaces. For each category, representative sensing mechanisms, photoelectrode architectures, and real-world applications-especially in the detection of food contaminants such as mycotoxins, antibiotics, and pesticide residues-are comprehensively discussed. Furthermore, key challenges and future directions are outlined. This review aims to provide a conceptual foundation and technical reference for advancing ratiometric PEC sensing technologies in food safety and beyond.
