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 origin of feed ingredients, particularly corn, can influence nutrient composition and availability, thereby affecting broiler growth performance and overall production efficiency. This study evaluated the effects of the dietary inclusion of different corn origins: United States (local) (USA-L), United States (reimported) (USA-R), Argentina (ARG), and Brazil (BRA) on broiler performance, nutrient digestibility, and processing yield from 1 to 35 d of age. A total of 1200 male broiler chicks (YPM × Ross 708) were randomly assigned to four dietary treatments, with each diet incorporating corn from a specific origin. Birds were housed in controlled environmental conditions and fed isocaloric, isoproteic diets formulated based on corn nutrient profiles from each origin. Body weight (BW), body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR) were assessed at 10, 21, and 35 d. On d 35, ileal digestibility of nutrients was assessed using titanium dioxide as an indigestible marker, and processing yields were measured on d 36. Results indicated no impact of corn origin on BW or BWG during the grow-out. However, FI was greater in broilers fed with diets containing corn from ARG and BRA compared to corn from USA-L from 1 to 35 d (
