Assessing Class 1 Integron Presence in Poultry Litter Amended with Wood Biochar and Wood Vinegar.
Article in Current microbiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Class 1 integrons are mobile genetic elements that facilitate the spread of antibiotic resistance genes among bacteria. The use of prophylactic antibiotics has resulted in the rise of antibiotic resistance genes accumulating in a wide range of settings, including poultry houses and the agricultural fields where poultry litter is applied as a fertilizer. Biochar and wood vinegar are forest products wastes that have generated increasing attention as additives to agricultural soils. The objectives of this study were to observe the prevalence of class 1 integrons in poultry litter blended with biochar and wood vinegar over time and to verify a modified class 1 integron screening assay. Poultry litter blends were sampled and screened for class 1 integrons using polymerase chain reaction, and 80 products, 79 of which showed positive, were sent for DNA sequencing. The GenBank® BLAST database was used to verify the presence of the class 1 integron-integrase gene (intI1). There was no change in prevalence over time in poultry litter blends. Out of 79 PCR products that were intI1 positive, 78 showed at least 95% sequence identity to intI1 encoding bacteria and 64 showed at least 97% sequence identity. This indicates that this method was effective for conducting baseline surveillance of class 1 integrons in poultry litter and poultry litter-blended biochar and/or wood vinegar. Most significantly, class 1 integron prevalence did not decrease over time, further supporting the recalcitrance of these elements and the need for improved monitoring systems.
