Stratified and combined analysis of the quality of lumbar spinal stenosis-related videos on major Chinese short video platforms.

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: Lumbar spinal stenosis (LSS) is a degenerative disorder in which narrowing of the spinal canal compresses neural elements, causing pain, numbness, and limited mobility. With the rapid growth of Chinese short video platforms (TikTok, Bilibili, Xiaohongshu, Kwai, and WeChat), the public increasingly relies on short videos for LSS-related health information. However, the quality of such content has not been systematically evaluated. Methods: This cross-sectional content analysis searched each of five platforms using "lumbar spinal stenosis," screened the top 100 results, and included 412 videos after applying predefined criteria. Basic characteristics and engagement metrics were extracted. Analyses were stratified by platform, uploader type, and video category. Video quality and reliability were assessed using the Global Quality Score (GQS), modified DISCERN (mDISCERN), and JAMA benchmark criteria. Spearman correlation analysis examined associations between video characteristics and quality scores. Results: High-quality content was concentrated on Bilibili and WeChat, particularly scientific explanations and professional course videos uploaded by healthcare professionals, whereas Kwai showed consistently low GQS scores across uploader types and categories. Video duration was moderately and positively correlated with GQS ( Conclusions: Overall, the quality and reliability of LSS-related short videos on major Chinese platforms are suboptimal, with marked inter-platform variation. Content from non-professional uploaders and personal experience-focused videos tended to be of lower quality. Healthcare professionals and medical institutions should actively disseminate evidence-based LSS information via short video platforms, and viewers should preferentially seek credible, verifiable sources.
