Effects of a direct fed microbial and xylanase enzyme blend on Salmonella Typhimurium colonization, antioxidant status, and performance in broiler chickens.
Article in Poultry science, 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
Salmonella is a major issue in the poultry industry, with infected flocks causing contaminated carcasses and products leading to outbreaks. Blends of enzymes and direct fed microbials (DFMs) have shown potential to reduce Salmonella colonization in broilers. This study investigated the effects of supplementing DFMs and enzyme blends under low-energy nutritional status and S. Typhimurium challenge on performance, Salmonella colonization and prevalence, and antioxidant status of broilers. A total of 256 day-old broiler chicks were randomly allocated to four dietary treatment groups (8 birds/cage, 8 replicate cages) and fed a standard energy diet as positive control (PC; 2,975 kcal/kg ME), a reduced energy diet as negative control (NC; 2,875 kcal/kg ME), the NC diet supplemented with a Bacillus spp. probiotic and xylanase blend (EFS), or the NC diet supplemented with a blend of multi-species probiotic and xylanase (BAX). Performance parameters were measured per cage on d 0, 7, 17, and 28. All birds were challenged with 1 × 10
