Biogas production and microbial profile estimation in bioreactor landfills.
Article in Frontiers in chemistry, 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
Introduction: This study investigated the municipal solid waste (MSW) biodegradation process, simulating landfill conditions using a bioreactor. A core objective was to identify key markers in leachate that could forecast the methane (CH Methods: A bioreactor was utilized to replicate the landfill's MSW biodegradation process. Research workers analyzed the relationship between the methanogenic process and the properties of leachate from anaerobic digestion. To investigate the underlying causes of inhibition, we compared the features and differences in the microbial community structure of leachate samples from different reaction periods and solid samples (end-state MSW and cover layer). Results: The biogas production potential was found to be 74.36 L kg Discussion: The findings indicate that due to ammonia buildup, the fermentation system became unstable when the TOC/TN value fell below 13. The absence of Nitrospirain leachate is identified as a critical factor disrupting the nitrogen cycle. Therefore, inoculation with Nitrospira-containing agents is proposed as crucial for maintaining system stability and enhancing treatment efficiency. The intermediate cover layer, harboring greater microbial diversity, contributed to enhanced anaerobic digestion and supported increased system stability, functioning as a vital biochemical reaction zone. These insights provide recommendations for enhancing the AD system's CH
