Effectiveness of education on radiation exposure for medical students prior to clinical clerkship.
Article in Japanese journal of radiology, 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
purposeThe widespread use of radiation in diagnostic imaging, interventional procedures, and radiotherapy requires robust radiation safety education. Despite its importance, medical students in Japan and other countries have limited awareness of radiation protection. In Japan, radiation safety education is essential due to recent legislative changes that position medical students as "student doctors" and expand their clinical responsibilities. The purpose of this study was to evaluate the knowledge, concerns, and anxieties of 5th-year medical students regarding radiation exposure before clinical training, and to evaluate the impact of a lecture-style intervention on these parameters. MATERIALS AND
methodsA 20-min lecture on radiation safety was given to 95 fifth-year students at Nara Medical University immediately before clinical training. The lecture covered the basic concepts of radiation biology, legal regulations, radiation risks, and protective measures. A 25-item questionnaire using a five-point Likert scale was administered before and after the lecture. Exploratory factor analysis was conducted on the data, and mixed-design analysis of variance (ANOVA) was used to evaluate changes in the main factors identified by exploratory factor analysis. Subgroup analysis was also conducted based on gender and the selected clinical department.
resultsExploratory factor analysis identified four main factors: anxiety, interest, knowledge, and management of radiation exposure. After the lecture-based intervention, knowledge and management of radiation exposure scores increased significantly (p < .001), but interest did not change. There was no difference in score by gender.
conclusionLecture-based interventions can significantly improve senior medical students' knowledge and management skills regarding radiation safety. However, it was difficult to improve the interest of students who chose departments that were considered to have a low risk of radiation exposure. Our findings indicate the need for further development of educational strategies to improve awareness and education of radiation protection in clinical situations.
