1 · What the graph read from 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.

2 · The registry

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 purpose of this study was to investigate the effects of dietary supplementation with copra meal on growth performance, meat quality, and intestinal development in Wenchang chickens. A total of 480 healthy, 80-day-old female Wenchang chickens were randomly allocated to 4 groups, each with 6 replicates of 20 birds. The chickens in the control group (Con) received a basal diet, whereas the 3 experimental groups were fed the basal diet supplemented with 1.5%, 3.0%, or 6.0% copra meal for 40 days. The results indicated that the 1.5% group exhibited higher average daily gain (ADG) and lower feed-to-gain ratio (F/G) compared with the Con group. Additionally, dietary supplementation with 1.5%, 3.0%, or 6.0% copra meal reduced drip loss in both thigh and breast muscles. In the 1.5%, 3.0% and 6.0% group, the contents of C14:0 were significantly induced, and C14:1 were significantly increased in thigh muscle, compared with the Con group. Moreover, the 6.0% group demonstrated significantly greater villus height and villus-height-to-crypt-depth ratio in the jejunum, along with higher levels of propionic and butyric acids in the ileum. At the genus level, Turicibacter abundance was significantly lower in the 6.0% group, whereas Bacteroides and Barnesiella were significantly higher. These findings suggest that dietary supplementation with 6.0% copra meal reduces F/G and enhances meat quality and intestinal development in Wenchang chickens.
