Evaluation of the compostability and toxic effects on Hordeum vulgare and Cynodon dactylon plants of plastic bags manufactured with compostable plastics.
Article in PloS one, 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
Because of the problem related to the accumulation of plastic bags in the environment, polymers called "bioplastics" have been developed. These materials are designed to reintegrate quickly into the environment, reducing thus environmental damage. However, when testing disposable bags made with biopolymers using standardized methodologies, it has not been possible to observe that they satisfactorily meet the criteria to be considered compostable. The present study evaluated compliance with the compostability criteria according to international standards established by the International Organization for Standardization (ISO) of three certified compostable plastic bags (BioW, Comph and Ecol) manufactured with polybutylene adipate-co-terephthalate, polylactic acid and corn starch, performing chemical composition tests using attenuated total reflectance Fourier Transform infrared (ATR-FTIR) spectroscopy and inductively coupled plasma - optical emission spectroscopy (ICP-OES), and disintegration, biodegradation and ecotoxicity tests. The results showed that the three bags contain the polymers reported in their data sheet and possibly polyethylene. Likewise, all of them comply with the maximum permissible limit of metals. Comph and Ecol met the disintegration criteria. No bag met the aerobic biodegradation criterion, with Ecol showing the highest percentage (51%) and Comph the lowest (3%). None of the bags had toxic effects on plants and neither met the biodegradation criterion necessary to be considered 100% compostable.
