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
The Yangtze River, as the world's largest clean energy corridor, links key economic regions and plays a crucial role in inland waterway transportation. However, few studies have comprehensively evaluated the potential of the Yangtze River for cross-regional hydrogen transport. Here, we develop a comprehensive integrated power and hydrogen supply chain (IPHSC) optimization model to evaluate the potential of cross-regional hydrogen transport via the Yangtze River. The IPHSC optimization model covers the entire hydrogen production-storage-transportation-utilization chain through cross-sector modeling of energy, transportation, water scheduling, and environmental protection. Results show that, in the 2060 carbon neutrality scenario, the deployment of 62.2 kilotons of 574 differentiated liquid hydrogen (LH2) carrier ships could enable the transportation of 5,018 kilotons (1,512 million ton-km) of hydrogen annually, meeting nearly 20% of the total electrolytic hydrogen demand across eight riverine provinces. Unlike west-to-east electricity transmission in China, the central Yangtze River region is expected to become the main hub for hydrogen exports in the future. Compared with alternative methods such as transmission lines or pipelines, LH2 carrier ships offer the lowest energy supply costs, at 3 US cents/kWh for electricity and 5 US cents/kWh for hydrogen. Additionally, a full-parameter attribution analysis of over 40 factors is conducted to assess variations in supply costs. Our study offers a thorough evaluation of the feasibility and economic benefits of hydrogen transportation via inland waterways, providing a comprehensive, multi-sectoral coupling assessment framework for regions with well-established inland waterway networks, such as Europe and the United States.
