Content Quality, Reliability, and Factors Associated With Likes of Venous Thromboembolism-Related Short Videos on TikTok and Bilibili: A Cross-Platform Analysis.
Article in Clinical and applied thrombosis/hemostasis : official journal of the International Academy of Clinical and Applied Thrombosis/Hemostasis. 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
BackgroundShort-video platforms have become important sources of health information, but the quality and reliability of venous thromboembolism (VTE)-related short videos remain unclear. This study evaluated VTE-related short videos on TikTok and Bilibili and conducted an exploratory examination of factors associated with video likes.MethodsOn February 27, 2025, the top 150 videos from each platform were retrieved according to the platforms' default ranking algorithms. Video quality and reliability were assessed using the Global Quality Score (GQS), modified DISCERN (mDISCERN), and Medical Quality Video Evaluation Tool (MQ-VET). In an exploratory analysis, an eXtreme Gradient Boosting (XGBoost) model was developed to examine factors associated with video likes.ResultsA total of 184 videos were included, comprising 81 from Bilibili and 103 from TikTok. Bilibili videos were longer, covered more VTE-related topics, and had higher median numbers of saves and shares, as well as higher GQS, mDISCERN, and MQ-VET scores than TikTok videos. TikTok videos received more likes and comments, while videos from professional uploaders on TikTok demonstrated higher quality and reliability. In the exploratory XGBoost analysis, follower count contributed the most to predicting video likes, followed by days since upload and the use of subtitles.ConclusionThe overall quality and reliability of VTE-related short videos were suboptimal. Greater professional involvement and clearer reporting of evidence sources, references, and update information may enhance the educational value of online VTE-related short videos.
