From Print to Soil: Superworm-Degradable Organic Electrochemical Transistors via PEDOT:PSS-Clay Composites.

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 growing use of disposable electronics has intensified concerns regarding end-of-life electronic waste, highlighting an urgent need for devices that balance high functionality with sustainability. Herein, we report disposable printed organic electrochemical transistors (OECTs) featuring a worm-edible PEDOT:PSS-clay composite active layer. These devices are constructed entirely from components selected to reduce environmental burden: a chemically reinforced and hydrophobically modified paper substrate; printable electrodes derived from a cellulose nanofiber (CNF)-templated silver ink; and a PEDOT:PSS/montmorillonite (MMT) composite active layer that ensures both electrochemical performance and superworm-derived biodegradability. Despite the use of low-resolution printing and sustainable materials, the resultant OECT devices exhibit low-voltage but stable operation and decent electrical characteristics suitable for practical applications. Critically, we demonstrate that these fully integrated devices are edible at the device level and can be disposed of via superworm ingestion (
