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

As essential mineral elements for poultry nutrition, calcium and phosphorus are not only the main components of bones and eggshells, but also participate in physiological processes such as energy metabolism and cell signal transduction. Calcium and phosphorus are also important factors affecting feed cost, in addition to energy and crude protein. As the poultry industry continues to develop towards intensification and large-scale operation, the dietary levels of calcium and phosphorus have been continuously increasing, leading to problems such as raising feed costs and environmental risks. This article aims to review the precise nutritional roles of calcium and phosphorus and the synergistic effects and mechanisms in chicken. A comprehensive literature search was conducted in PubMed, Web of Science (WOS), Scopus, and China National Knowledge Infrastructure (CNKI) for peer-reviewed articles published in English and Chinese between January 2000 and June 2026. The initial search returned 41506 records. After exclusion of 5714 duplicates, 35512 articles were screened by title, abstract and keywords, and 280 were assessed in full text. Ultimately, 97 studies were included for qualitative synthesis. These studies included dose-response experiments conducted on broilers and layers from different geographical regions, as well as studies related to the mechanisms and review articles. Based on this, this article reviews the precise nutritional roles of calcium and phosphorus, the nutritional sensitivity indicators, the effects of dietary calcium and phosphorus on eggshell quality and bone development, the calcium and phosphorus requirements of different chicken breeds, the calcium-phosphorus synergistic effect and the related mechanisms, and proposes some nutritional regulation measures for dietary calcium and phosphorus. It also looks forward to future research directions, providing important references for the research and application of precise nutrition of calcium and phosphorus in the chicken industry.
