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

Zinc, as a cofactor for various metalloenzymes in poultry, is essential for skin integrity, immune function, and wound healing. This study optimized the synthesis conditions of organic collagen peptide-chelated zinc (oZn) and evaluated their efficacy in improving skin quality using meat duck models. Firstly, the optimal synthesis conditions of oZn (collagen peptide was mixed with Zn sulfate) were then identified using an L16 (4^4) orthogonal design, with a peptide-to-Zn ratio of 4:1, pH 5, 60°C, and 10-minute. Then, either inorganic Zn (iZn) or oZn supplementation (60 mg/kg) increased growth performance, skin Zn content, quality (piercing force and shear force), dermal thickness, collagen content, and upregulated skin proliferation-related genes (ELN, MAP3K7, and P63) mRNA expression compared with without Zn addition (Con) using meat duck models (P < 0.05). Proteomic profiling revealed 134 (Con-iZn) and 174 (Con-oZn) differentially expressed proteins (DEP) in skin involved in chromatin remodeling (P = 0.01) and ribosomal biogenesis (P = 0.02). Notably, oZn displayed superior efficacy in dermal properties through elevated collagen biosynthesis than iZn. In conclusion, optimized collagen peptide-zinc chelate (pH 5, 60°C, 10 min, 4:1 ratio) improved growth performance and skin quality in meat ducks. Organic zinc demonstrating greater efficacy through enhanced collagen biosynthesis and dermal thickness. These findings establish a theoretical basis for developing novel Zn sources as nutritional strategies to optimize skin health in meat duck.
