Giving Broiler Feathers a Good Fate. Optimization of Chemical Hydrolysis for the Production of a Hydrolysate Rich in Free Amino Acids.
Article in ACS omega, 2025. 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 poultry meat production chain generates considerable waste, especially feathers. Feathers, composed of low solubility, digestibility, and chemical stability keratins, pose a significant challenge for reuse. This study, however, has successfully optimized the alkaline hydrolysis process using sodium hydroxide, potassium hydroxide, and an equimolar combination under varying temperature and time conditions. The different hydrolysis conditions were statistically evaluated to identify critical optimization points. The errors between the predicted and experimentally acquired results were remarkably low, providing a high level of reliability for the process. They achieved higher protein hydrolysis rates (97.9% for NaOH, 96.7% for KOH, and 97.8% for the mixture). Analysis by
