Food-Based Electronics: Revisiting β-Carotene Organic Transistors.
Article in ACS applied materials & interfaces, 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
Edible electronics offer a unique platform for developing devices made entirely from food-based materials that can be safely digested or excreted without environmental concerns. Yet, identifying semiconductors that are both food-based and capable of supporting efficient charge transport remains a challenge. In this work, we show that this hurdle can be overcome by applying structure-property insights developed in organic electronics to natural compounds, revealing how a material previously discarded for electronic applications and largely present in vegetables, β-carotene, can be tuned into a viable semiconductor. Beyond its implications for edible electronics, this approach also highlights the broader potential of renewable, nature-derived materials as building blocks for sustainable technologies.
