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 transition from conventional cage systems to cage-free egg production in China remains limited despite apparently increasing consumer demand for cage-free eggs. This study interviewed 15 large-scale Chinese egg producers using cages and/or cage-free systems (i.e. single-, multi-tier and free-range) to investigate the perceived challenges and opportunities during the transition. The cage farms' scales range from 110,000 to 30 million, while the cage-free farms keep between 12,000 and 300,000 laying hens. Drawing upon the COM-B model of the Behaviour Change Wheel, this study explored how producers' Capabilities, Opportunities, and Motivations impact decision-making processes. Key findings reveal that cage and cage-free producers considered consumer demand and profitability as primary drivers for adopting cage-free systems. While free-range producers were more confident in the market, barn system producers faced greater uncertainty due to limited engagement from corporate buyers. Moreover, these cage-free producers believed reliable certification and labelling schemes to be critical for building consumer trust and ensuring the success of cage-free operations. All the participants perceived access to sufficient land and financial resources to be essential for a successful transition. While most studies propose education as a long-term strategy to promote the growth of the cage-free egg sector, our findings are the first to highlight that engaging corporate buyers and establishing trustworthy certification schemes are the most crucial short-term interventions required to drive the development of large-scale cage-free farms and support sustained improvements in animal welfare in China.
