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
Background: Typhoons are one of the most common natural disasters, seriously jeopardizing public safety. Risk perception, defined as the subjective judgment that people make about the characteristics and severity of a risk, plays a crucial role in public preparedness behavior during typhoon disasters. However, there is a lack of knowledge regarding public risk perception and its influencing factors in typhoon-prone areas. This study aims to fill the knowledge gap by evaluating the public risk perception and key factors associated with perceptions among the general public. In addition, the relationship between the disaster knowledge, official trust, sources of warning information, and risk perception will be explored. Methods: A cross-sectional study was conducted from October 2024 to January 2025 with participants from Hainan Island, China. The target population consisted of residents aged 18 years and older who had resided on Hainan Island for over half a year ( Results: Out of 517 participants surveyed, Data were comprised of 517 valid responses from 11 major administration areas across Hainan Island. Disaster knowledge, official trust, sources of warning information were significantly correlated with public risk perception. SEM results revealed that the model fit the data well. The results showed that disaster knowledge and official trust are directly and positively associated with risk perception (the unstandardized coefficients of direct path are 0.331 and 0.467 respectively, Conclusion: This study indicates that warning information does not directly correlate with risk perception; their relationship is fully mediated by disaster knowledge and official trust. To improve disaster risk perception, government agencies might consider strengthening institutional credibility, diversifying warning channels, and enhancing public disaster education.
