Biodegradation of PHBV-based biocomposites in two different marine environments of the Mediterranean Sea.
Article in Biodegradation, 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
Plastic pollution has become one of the most pressing environmental issues worldwide, with large amounts of conventional plastics accumulating in terrestrial and marine ecosystems due to their persistence and ineffective waste management. Developing and understanding the biodegradation behavior of environmentally friendly alternatives, such as bioplastics, is therefore crucial to mitigate this problem. In this context, the degradation of PHBV-based biocomposites containing purified cellulose (TC), wood flour (WF), and almond shell (AS) fibers have been investigated and compared with neat PHBV in two Mediterranean marine locations-a port and the open sea, within the same geographic region. Changes in weight, surface morphology, surface roughness, surface chemistry, and mechanical properties were monitored and periodically evaluated over 18 months of seawater exposure at the two sites. After 18 months of immersion, PHBV/AS showed the highest disintegration degree (88% for 150 µm films and 33% for 500 µm sheets), with the port environment promoting up to a two- to three-fold higher biodegradation rate compared to the open sea. Additionally, mineralization was studied in lab-simulated marine conditions by tracking CO
