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

Waste feathers (WF), major poultry industry by-product, pose health and environmental risks if mismanaged, yet contain valuable protein. Traditional feather protein extraction methods have several limitations: excessive time and energy requirements, low yield, and poor digestibility. This study introduces a novel method using a deep eutectic solvent (DES) to effectively degrade WF into low molecular weight peptides (400-600 Da). This method achieved 79.97 % dissolution rate and 50.26 % extraction yield within 2 h at 92 °C. Critically, in vitro digestion tests showed that the free amino acid release from feather peptides (FP) was 241.08 μg/mL, 63.9 % higher than that from fishmeal (147.06 μg/mL), demonstrating substantially higher digestibility than both standard fishmeal and traditionally processed feathers. This DES-based approach provides an efficient, eco-friendly, and economical route to transform problematic feather waste into a highly digestible and functional animal feed protein, promoting circular economy principles.
