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 interconnection of transport infrastructure is a priority area under the Belt and Road Initiative and holds significant implications for global socio-economic development. Air network connectivity plays a vital role in shaping transport efficiency. From a global air transport network perspective, this study investigates the spatial evolution of China's international air cargo network connectivity between 1996 and 2019. Using OAG global flight schedule data from five representative years (1996, 2002, 2008, 2014, and 2019), we apply complex network theory and graph-theoretical methods, incorporating tools such as UciNet and ArcMap. Three key indicators, weighted degree centrality, betweenness centrality, and K-core decomposition, are employed to analyze changes, evolutionary patterns, and driving factors of network connectivity. The findings reveal that with shifting global economic and policy environments, China's air cargo network connectivity has gradually strengthened, with an increasingly hierarchical structure and more diversified and efficient network forms. Freighter and bellyhold cargo routes differ markedly in network evolution: freighter routes display a stable core-periphery structure shaped by industrial and policy factors, while bellyhold routes evolve path-dependently alongside passenger services, shifting from concentration to decentralization. This study demonstrates the dynamic restructuring of China's international air cargo connectivity under the dual forces of globalization and regionalization. It provides theoretical insights and decision-making references for enhancing China's air transport efficiency and supporting the implementation of the Belt and Road vision, thereby contributing to the advancement of global integration.
