Research on New Methods of Topic Mining and Topic Prediction for Medical Preprints on Emerging Infectious Diseases.
Article in Cureus, 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
Background and purpose To cope with the continuous risk of sudden infectious diseases and achieve real-time monitoring of research trends, this paper proposes a new prediction framework that combines public attention indicators with medical preprint topic analysis. In view of the lag problem of traditional topic prediction methods, this paper introduces Google Trends data to improve the timeliness of prediction. Methods In this study, 18,060 COVID-19-related preprint abstracts were obtained from the medRxiv platform using web crawler technology. The unsupervised probabilistic modeling method, Latent Dirichlet Allocation (LDA), was used to extract the latent topic structure in the text. In order to analyze the dynamic relationship between research topic intensity and public attention, the Autoregressive Distributed Lag (ARDL) model, which can simultaneously process I(0) and I(1) time series, was introduced. Text data preprocessing included word segmentation, stop word removal, lemmatization, and synonym standardization. Time series data were aggregated by week, the original data were logarithmized, the Augmented Dickey-Fuller (ADF) unit root test was used to determine stationarity, and non-stationary variables were differenced. The models were implemented in Python and EViews10, respectively. Results Seven major research topics were identified through LDA modeling. ARDL analysis verified that there was a significant dynamic relationship between public search trends and topic intensity, and that the model had good predictive performance. Conclusion This study combined LDA with ARDL models to construct a real-time prediction method that can be used to track the evolution of medical preprint topics. This method has important theoretical and practical significance in the field of public health informatics and provides feasible predictive support for the monitoring and prevention of future infectious diseases.
