The quality and content of cerebral aneurysm related short videos on Douyin: a cross-sectional observational study.
Observational study in Scientific reports, 2026. 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
Cerebral aneurysm is a common cerebrovascular disease with a poor prognosis after rupture. This highlights the critical importance of early detection and risk factor management. Douyin has become an important channel for disseminating medical information, but the quality of video content on such platforms remains unclear. This study aims to evaluate the content, quality, and reliability of short videos related to cerebral aneurysm on Douyin. A cross-sectional analysis was conducted on 100 short videos related to cerebral aneurysm on Douyin (the Chinese version of TikTok). Video characteristics, content, uploader type, and interaction data (likes, comments, favorites, and shares) were extracted. Video quality and reliability were assessed using the Global Quality Score (GQS) and modified DISCERN (mDISCERN) tools. Videos were classified by content and emotional tone, and engagement metrics and quality scores were compared across different categories. Correlation analysis was performed between video metrics and quality scores. Videos were generally short (median: 77 s), but user engagement was high. Most videos were uploaded by cerebrovascular specialists. Educational videos scored better on GQS than case-sharing videos, but no significant difference was found in mDISCERN scores. Regarding interaction data, case-sharing videos had significantly more favorites than educational videos, but no differences were observed in other engagement metrics. Videos were further categorized by emotional tone (positive, negative, neutral), and no differences were found in quality scores or engagement metrics across these categories. Meanwhile, positive correlations were observed among engagement metrics (likes, favorites, comments, and shares). Douyin videos related to cerebral aneurysm show high engagement but slightly insufficient reliability in content. Improving video quality is essential to enhance the educational value of health information shared on the Douyin platform.
