Quality, reliability, and content analysis of short videos concerning lipid-lowering drugs on TikTok and Bilibili in China: 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
Lipid-lowering therapy is crucial for cardiovascular disease prevention, yet adherence is suboptimal due to concerns about side effects. Short video platforms are key health information sources in China, but content quality regarding pharmacotherapy remains under-investigated. This study aimed to systematically evaluate the quality, reliability, and content of short videos regarding "lipid-lowering drugs" on TikTok and Bilibili. A cross-sectional study was conducted in December 2025. The top 150 videos retrieved via the keyword "lipid-lowering drugs" from each platform were screened. A total of 199 videos meeting inclusion criteria were analyzed. Two independent researchers evaluated uploader profiles, content coverage, and interaction metrics. Video quality was assessed using the Global Quality Scale (GQS) and reliability via the modified DISCERN (mDISCERN) tool. Medical professionals dominated the ecosystem (90%), reaching 100% on TikTok. While videos frequently covered mechanisms (63.8%) and indications (54.3%), critical safety information regarding drug interactions (11.6%) and contraindications (11.1%) was systematically omitted. TikTok videos demonstrated significantly higher GQS scores than Bilibili (median 3.00 vs 2.00, P = .007), yet evidentiary reliability (mDISCERN) remained moderate across both (median 2.00). Crucially, user interaction metrics correlated significantly with production quality (GQS) but showed no association with reliability (mDISCERN). Despite professional dominance, online lipid-lowering drug information suffers from a "safety silence," lacking comprehensive contraindication warnings. A "popularity paradox" exists where engagement reflects presentation skills rather than medical reliability. Healthcare providers must prioritize safety profiles in digital education, and patients should be cautioned against judging accuracy by popularity.
