Research Note: The use of ammonia gas for Salmonella control in poultry litters.
Article in Poultry science, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
A new poultry litter disinfection methodology against pathogenic Salmonella spp. serovars using gaseous ammonia is proposed in this study. In the laboratory, the poultry litter was disposed into plastic containers and experimentally contaminated with 3 Salmonella spp. serovars separately. Positive and negative control groups were tested. With a system of hoses, 1% gaseous ammonia was injected into the containers in cycles for 48 h. Samples of the poultry litter were collected and submitted to bacteriological analysis. For the second part, we selected a broiler poultry farm with positive litters for Salmonella heidelberg in 2 houses. The littler was treated by gaseous ammonia in a concentration of 2,411 ppm and wrapped with a plastic cover for 48 h during the sanitary break. After the treatment, a new broiler batch was housedand swab samples were collected in the 25-day-old. After the action of the gaseous compound, there was no reisolation of the serovars, and the batches housed on the ammonia-treated litter no longer showed positive results for Salmonella. The total elimination of the pathogenic microorganisms by the new method suggests that the controlled use of ammonia gas in poultry litter may represent a viable disinfection technique.
