The anaerobic digestion microbiome is robust toward variation in the waste activated sludge feed.
Article in ISME communications, 2026. 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
Anaerobic digestion stands out as the foremost technology for maximizing the valorization of waste activated sludge (WAS) to recover energy and recover resources. The physical/chemical and microbial makeup of WAS is susceptible to seasonal fluctuations, due to the open-air nature of wastewater treatment facilities, potentially impacting subsequent digester performance and the quality of the resulting digestate. This study delved into a comprehensive analysis of both the initial WAS and the digestate produced by 12 full-scale digesters during both a summer and winter sampling campaign. A significant influence of seasonal variations was observed on the physical/chemical and microbial composition of WAS. Interestingly, the digestate microbiome exhibited a high resilience with minimal seasonal fluctuations, but instead showed variations between different digesters. In summary, this research demonstrates that while WAS composition manifests in specific physical/chemical attributes, it does not exert a discernible influence on the microbial composition of the resulting digestate.
