The quality and reliability of osteosarcoma information on TikTok and Bilibili: A cross-sectional study.

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: Osteosarcoma is a rare and aggressive bone malignancy, yet public awareness remains insufficient. As social media platforms have become key sources of health information, this study aims to evaluate the quality and reliability of osteosarcoma-related videos on these platforms. Methods: This study collected 100 osteosarcoma-related videos from each platform, TikTok and Bilibili, based on their default ranking, resulting in 200 videos initially screened and 183 included after exclusions. Video characteristics were collected, including duration, likes, saves, comments, and shares. The Global Quality Scale (GQS) and Modified Discrimination Score (mDISCERN) were used to assess video quality and reliability. The completeness score (CS) was applied to evaluate five key aspects of the disease: etiology, clinical manifestations, diagnosis, treatment, and diagnosis. Finally, correlation analysis is carried out to explore the relationship among video features, audience engagement indicators, and video quality. Results: A total of 183 osteosarcoma-related videos were included. Clinical manifestations, treatment, and diagnosis were the most frequently addressed topics, whereas etiology and prognosis received comparatively less attention. TikTok videos had a median GQS of 2(Q1 = 2.00, Q3 = 3.00), a median mDISCERN of 3 (Q1 = 2.00, Q3 = 4.00), and a median CS of 4 (Q1 = 2.00, Q3 = 4.00). In contrast, Bilibili videos demonstrated higher quality, with a median GQS of 3 (Q2 = 2.00, Q3 = 3.00), a median mDISCERN of 3 (Q1 = 3.00, Q3 = 4.00), and a median CS of 4 (Q1 = 3.00, Q3 = 6.00). Videos produced by healthcare professionals achieved significantly higher scores compared to those uploaded by non-professionals ( Conclusion: In conclusion, the overall quality and reliability of osteosarcoma-related videos on short video platforms were low. Videos uploaded by healthcare professionals and those on the Bilibili platform demonstrated relatively higher quality. These findings highlight the necessity of strengthening the regulation of health-related content on short video platforms and promoting greater involvement of healthcare professionals.
