The inverse relationship between popularity and quality in developmental dysplasia of the hip videos: A cross-sectional analysis of TikTok and Bilibili.

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
Objective: This study evaluated the quality and reliability of unassessed DDH health information for parents on prominent short video platforms like Bilibili and TikTok, where accurate data is crucial for early intervention. Methods: We conducted a cross-sectional study, analyzing 125 eligible DDH-related short videos from Bilibili and TikTok. Video characteristics, author types, and interaction metrics were extracted. Content quality was assessed by medical professionals using the modified DISCERN (mDISCERN) and Global Quality Score (GQS) tools. Ordinal logistic regression identified factors influencing quality. Results: Significant inter-platform differences were found in video characteristics and engagement. While both platforms showed generally high quality, Bilibili slightly outperformed TikTok. Author professionalism (GQS OR=4.025; mDISCERN OR=5.585) and video duration (GQS OR=1.010; mDISCERN OR=1.010) were significant positive predictors of quality. Critically, a negative correlation existed between higher interaction metrics (likes, comments, shares, views) and perceived video quality. Conclusion: While short video platforms significantly impact DDH health information, quality varies, with author professionalism and video duration predicting higher standards, yet popular videos often lack scientific rigor, highlighting an urgent need for enhanced quality control and expert-driven content.
