Effects of Different Cultivated Land Utilization Types on Heavy Metal Characteristics and Microbial Community Composition.
Article in ACS omega, 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
We conducted a comprehensive analysis of soil heavy metals and the structure of the microbial community in various cultivated land types in an area with naturally high heavy metal content. 96 Topsoil and 20 soil profile samples were collected from agricultural soils: bare land (CK), corn (COR), paddy (RIC), and vegetable (VEG). The primary purpose of this investigation was to elucidate the underlying assembly mechanisms and key driving factors that influence dynamic changes in bacterial community composition across different cultivated land environments. Across all regions, substantial disparities were observed in bacterial diversity and levels of heavy metal contamination. The results of this study reveal that the average Cd and Cr levels in the four soil types were relatively high, with the greatest Cd contamination observed in the COR soil type. Notably, COR soils had the highest available As, Cd, Cr, Pb, and Zn levels compared to the other three types. Concerning bacterial diversity, the RIC soil type exhibited the highest levels, as demonstrated by high Shannon, Chao1, and ACE indices, compared to other land use types. Principal coordinate analysis (PCoA) and nonmetric multidimensional scaling (NMDS) results indicated that bacterial communities in RIC, VEG, and CK, COR soils showed a similar pattern. A deeper analysis of the microbial community revealed that
