Optimizing eggshell quality in extended laying periods: Insights and strategies.
Review in Animal nutrition (Zhongguo xu mu shou yi xue hui), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Extending the laying period in hens offers substantial financial and environmental benefits. However, maintaining stable egg quality, particularly eggshell quality, remains a significant challenge. This review summarizes the age-related changes in eggshell quality and, based on these changes, discusses potential strategies to help maintain eggshell quality during the extended laying period. Recent studies tracking the age-related changes in eggshell quality have highlighted the phased and complex nature of these alterations, with multifaceted modifications in the eggshell's multilayered structure and composition. These changes are primarily driven by physiological declines in key organs, such as the oviduct, skeleton, and intestines. To address these challenges, several effective strategies have been taken or proposed. These include optimizing dietary calcium levels and limestone particle size, as well as employing sequential feeding strategies to ensure adequate and timely calcium provision for eggshell formation. Additionally, supplementing with vitamin D
