Occurrence, load and transport-associated risk factors of Salmonella spp. in chickens sold in informal live bird markets in Centre-Nord Region, Burkina Faso.

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
Informal poultry trade is central to live-bird value chains in sub-Saharan Africa, but transport and handling practices may facilitate the spread of zoonotic pathogens such as Salmonella spp. This regional study assessed the occurrence, bacterial load, and transport-related risk factors of Salmonella spp. in indigenous village chickens (Gallus gallus domesticus) marketed through the Kaya live-bird market in the Centre-Nord Region of Burkina Faso. A cross-sectional survey was conducted among 49 poultry collectors. Four clinically healthy indigenous chickens (Gallus gallus domesticus) were selected from each collector's transported batch using a stratified random sampling procedure based on spatial position (front, middle, rear) yielding a total of 196 birds. Birds originated from smallholder households in surrounding villages and were selected for live sale. Cecal contents were analyzed for Salmonella spp. using ISO 6579:2012 protocols, bacterial loads were quantified by the Most Probable Number method, and isolates were confirmed by MALDI-TOF MS. Structured interviews documented collector characteristics, sourcing, transport, hygiene, and biosecurity. Logistic regression identified factors associated with Salmonella occurrence, while linear regression assessed predictors of bacterial load. Salmonella spp. was detected in 41.3% of chickens, with 59.2% of collectors having at least one positive bird. Transporting 21-50 birds and collectors having verified the vaccination status of birds when collecting chickens were associated with higher odds of detection. Higher bacterial loads were linked to temporary stops during collection or transport and reuse of dedicated work clothing without proper cleaning. This regional survey highlights the collector and live-bird market stage as a critical interface for Salmonella circulation in village poultry systems. Practical recommendation include reducing overcrowding during transport, improving confinement and hygiene practices, and strengthening biosecurity measures among poultry collectors.
