The impact of free trade port construction on regional import and export: Evidence from Hainan.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 construction of the Hainan Free Trade Port (HFTP) represents one of the most advanced regional development models explored by China. This study clarifies the concept of the free trade port and analyzes it from a trade perspective. Our empirical results show that the construction of the free trade port has significantly increased trade volumes, enhanced the diversification of products, and reduced the volatility of exports. A marked short-term surge in export volumes was observed immediately after the policy's implementation. Moreover, the effects of the free trade port's construction on trade are heterogeneous when viewed through the lens of product categorization.
