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

This study investigated the effects of supplementing diets for Shan Partridge Ducks (n = 720) with 1%, 2%, or 4% beef tallow, coconut oil, or a 1:1 ratio of the two on production performance, egg quality, and serum biochemistry over 12 weeks. Compared with the control group, dietary supplementation with coconut oil, beef tallow, or mixed oil significantly improved laying rate and daily egg mass and reduced FCR, with the best overall performance at the 2% inclusion level. While most egg quality parameters remained stable, the egg shape index was reduced at the 4% inclusion level. Serum analysis revealed that coconut oil supplementation elevated total protein and total cholesterol levels, suggesting a distinct metabolic influence. However, no significant increase in the liver enzyme ALT indicated an absence of overt hepatic stress. A significant interaction was found between oil type and level for egg weight. Furthermore, all oil supplements preserved egg storage stability over 28 days. In conclusion, dietary supplementation with 1–2% beef tallow or a mixed oil is recommended to enhance productivity and economic efficiency in commercial duck egg production without compromising egg quality or metabolic health.
