Interdisciplinary integration in public health emergency education: learning outcomes following a curriculum reform for preventive medicine undergraduates.

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: Developing a public health workforce with strong emergency response capacity is an important goal of medical education reform. However, evidence remains limited regarding how interdisciplinary and practice-oriented curricular reforms influence emergency preparedness-related knowledge acquisition among preventive medicine undergraduates. This study evaluated the effects of a curriculum reform based on an interdisciplinary, integrative, and collaborative training model. Methods: A cross-sectional study was conducted among 400 fourth-year undergraduate students majoring in preventive medicine at a medical university in China, including the 2017, 2018, 2020, and 2021 cohorts, with 100 students from each cohort. The 2017 and 2018 cohorts were classified as the pre-reform group, and the 2020 and 2021 cohorts as the post-reform group. Data were collected using an anonymous structured questionnaire covering academic characteristics, self-perceived emergency response competence, objective knowledge performance, and satisfaction with educational resources. Group comparisons, multivariable linear regression, and machine learning analyses were performed. Random Forest, Decision Tree, XGBoost, and LightGBM models were compared, and SHAP was used to interpret the best-performing model. Results: Compared with the pre-reform group, the post-reform group reported significantly greater participation in interdisciplinary courses, virtual simulation training, emergency drills, research projects, internship experience, and dual-mentor guidance. They also showed higher competence scores (36.05 ± 9.46 vs. 31.68 ± 9.89), higher satisfaction scores (21.52 ± 6.06 vs. 19.32 ± 6.41), and better objective knowledge performance (6.76 ± 1.50 vs. 5.11 ± 1.78), with all differences reaching statistical significance. In multivariable regression, interdisciplinary courses (β = 0.800, Conclusion: An interdisciplinary and practice-oriented curriculum reform was associated with improved emergency preparedness-related knowledge acquisition among preventive medicine undergraduates. Interdisciplinary coursework, virtual simulation, and internship experience appeared to be important factors associated with better performance. These findings support the value of integrated training strategies in public health emergency education and may inform future curriculum optimization.
