1 · What the graph read from it

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.

2 · The registry

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: The amount of online medical information available is rapidly growing and YouTube is considered as the most popular source of healthcare information nowadays. However, no study has been conducted to comprehensively evaluate YouTube videos related to temporomandibular disorders (TMD). So this study aimed to evaluate the content and quality of YouTube videos as a source of medical information on TMD. Method: A total of 237 YouTube videos that were systematically searched using five keywords (temporomandibular disorders, tmd, temporomandibular joint, tmj, and jaw joint) were included. Included videos were categorized by purpose and source for analysis. The quality (DISCERN, Health on the Net (HON), Ensuring Quality Information for Patients (EQIP), and Global Quality Scale (GQS)) and scientific accuracy of video contents were evaluated. Results: Total content, DISCERN, HON, EQIP, and GQS scores were 7.5%, 38.9%, 35.2%, 53.0%, and 48.6% of the maximum possible score, respectively. Only 69 videos (29.1%) were considered as "useful" for patients. News media, physician, and medical source videos showed higher evaluation scores than others. Quality evaluation scores were not significantly correlated or negatively correlated with public preference indices. In the ROC curve analysis, content and DISCERN score showed above excellent discrimination ability for high-quality videos based on GQS ( Conclusions: YouTube videos related to TMD contained low quality and scientifically inaccurate information that could negatively influence patients with TMD.
