Hidden middle governance reduces antibiotic residue health risks and food loss in aquatic supply chains.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
The "hidden middle" of food supply chains, referring to the small- and medium-scale intermediaries linking producers to markets, often obscures food safety risks and exacerbates losses. Integrating aquatic product testing data from 247 Chinese prefectures (2015-2022), we assessed the cross-regional impact of antibiotic residues (ARs) through the hidden middle of China's aquatic supply chains. We found that AR above legal limits caused 44,200 tons of food loss and health risks exceeding safe thresholds in six provinces. We then developed an optimization model to allocate sampling resources, resulting in 14,702 tons of food loss reduction and 77% decrease in health risks. Relative to current monitoring schemes, the optimized strategy delivered an additional 6,951-ton reduction in food loss and a 17% larger risk reduction per province per year. Our results demonstrate that focusing governance on AR spread through the hidden middle can improve food safety and reduce risks to food security and public health.
