Exploring the regional layout characteristics of ancient Chinese postal system in coastal areas based on AHP-CRITIC evaluation approach.
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
In ancient China, as the only transmission network, the postal system enabled long-distance delivery of information and supplies, providing information support for the development of ancient society. Delivery efficiency determined whether information and supplies could arrive at the fastest speed, reflected the level of regional transmission capacity, and served as an effective indicator for understanding the underlying logic of the postal system's regional layout. In this study, the concept of accessibility was introduced into the regional layout analysis of the postal system, and a hierarchical evaluation model was constructed based on the AHP-CRITIC (Analytic Hierarchy Process - Criteria Importance Though Intercriteria Correlation) composite weighting method. Then, the accessibility of the postal system in three typical areas of coastal defense front-line, transportation hub, and administrative center was qualitatively and quantitatively analyzed, and the differential characteristics of their accessibility and regional layout were summarized, so as to explore the layout logic of the postal system during the Ming Dynasty.
