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
Introduction: In line with China's "Dual Carbon" goals, achieving a green transformation of the healthcare system is imperative. This study aims to identify the factors driving energy use and to explore energy-saving strategies in large tertiary general hospitals across various architectural climate zones, thereby providing insights for sustainable development within the healthcare sector. Methods: Adopting a research design of "quantitative as the main approach, supplemented by qualitative" methods, we integrated data analysis, field surveys, and questionnaires. The study examined 12 tertiary general hospitals in Jiangsu Province from 2022 to 2023, collecting on-site building data and energy management information. Data analysis combined Spearman correlation analysis with findings from the questionnaire surveys. Results: The analysis revealed that hospitals in different climate zones exhibited similar quarterly patterns of energy use, but the key correlative factors varied significantly. Specifically, energy consumption in cold zones was primarily affected by operational scale, whereas in hot-summer-cold-winter zones, it was influenced by both hospital size and external temperature. Field surveys indicated that although all sampled hospitals had implemented some energy-saving technologies and management systems, none had installed real-time online energy monitoring systems. Conclusion: To establish efficient, low-carbon, and resilient hospitals, tailored strategies are recommended. For cold zones, the focus should be on optimizing energy structures, building design, and facility layout. For hot-summer-cold-winter zones, improving building insulation is crucial. Furthermore, accelerating investment in intelligent carbon-monitoring systems, managing energy hardware upgrades at the source, and enhancing staff energy-saving awareness are essential steps forward.
