Survival and clearance dynamics of Salmonella in litter, carcasses, and internal organs of chickens fed different dietary fat sources.
Article in Poultry science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The study evaluated the efficacy of four different fat sources in broiler feed on Salmonella presence in litter, spleen, liver, ceca, and carcasses. In this study, 1152, day-old chicks were allocated into four different treatments randomized among 48 pens. Fat source-based treatments included Soy Oil (T1), Poultry Fat (T2), Soap Stock (T3), and Palm Oil (T4). All birds were orally challenged on day 7 with 10^8 CFU of S. Enteritidis and S. Typhimurium cocktail. On days 14, 21, 28, 35, and 42, litter was sampled from each pen using boot swabs and spleen, liver, and cecal contents were sampled from one bird from each pen for Salmonella recovery. On day 43, 16 post-pick carcass rinsates per treatment were collected for Salmonella recovery. Data was analyzed using PROC GLM of SAS and Chi-square test in R. On day 14, Salmonella was detected from 16 %, 25 %, 41 %, and 33 % of spleen and 83 %, 66 %, 50 %, and 75 % of liver samples from T1, T2, T3, and T4, respectively (P > 0.05). Salmonella prevalence decreased in liver to 0 % at day 42 in all treatments except for 1 liver from T1. At day 14, cecal contents were 92 %, 83 %, 92 %, and 92 % Salmonella positive for T1, T2, T3, and T4 with an average of 3.5 to 4.6 log
