Effects of long-term biochar application combined with chemical fertilization on the nitrifier community in tobacco plantation soil.
Article in Frontiers in microbiology, 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
Soil nitrogen (N) plays a critical role in plant nutrition and is regulated by the process of nitrification. Biochar can enhance soil N concentration and is hypothesized to influence nitrification, particularly when applied in combination with chemical fertilizers. Although, several studies have documented the effects of biochar and fertilizer combinations on nitrifying microbial communities, the underlying mechanisms remain poorly understood. In this study, the abundances of ammonia-oxidizing archaea (AOA) in the BT3 (15 t/ha) and BT5 (40 t/ha) treatments, and ammonia-oxidizing bacteria (AOB) in the BT4 (20 t/ha) treatment, were significantly higher than in fertilizer-only treatments. In contrast, nitrite-oxidizing bacteria (NOB) in the BT2 (5 t/ha) treatment exhibited the most significant difference (
