A two-layer network model of the evolution of public risk perception of emerging technologies.

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
To fully comprehend public understanding of emerging technologies and their risks, from the stakeholder perspective, this study categorizes the public into primary and secondary stakeholders. Considering the impact of the spread of risk events on public risk perception of emerging technologies, this study adopts complex network theory to construct a two-layer network model consisting of "the spread of risk events-the evolution of public risk perception" of emerging technologies. The evolutionary threshold of public risk perception is analysed using the microscopic Markov chain approach. The influence of public composition and the spread of risk events on the evolution of risk perception is further verified through a simulation. The results of the study are as follows: First, public risk perception of emerging technologies tends to stabilise quickly. Second, the threshold and steady state of the evolution of public risk perception are influenced by the spread of risk events. Third, as the proportion of primary stakeholders or risk perception gap between primary and secondary stakeholders increases, the threshold for the evolution of public risk perception of emerging technologies increases, and the proportion of the public who think that emerging technologies are risky gradually decreases.
