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

backgroundSocial media platforms, initially developed for recreational use, have evolved into major sources for disseminating information, including medical information for patients and healthcare providers in many disciplines. This study aimed to evaluate the educational potential of YouTube® videos in teaching tracheal intubation to first-year anesthesiology residents.

methodsThis study was approved by the Ethical Committee of "University Federico II-AORN A. Cardarelli" (protocol no. 00010735). We analyzed the first 10 YouTube videos identified via the search term "tracheal intubation." Each video was evaluated for misinformation and informational completeness via a 5-item Likert scale. After providing written consent, fifty-seven first-year anesthesiology residents watched these videos and completed a 22-item questionnaire before and after viewing. Each correct answer received one point, whereas incorrect answers received 0 points, allowing for comparisons of knowledge acquisition.

resultsThe videos exhibited moderate quality (median score, 3; range, 1-5) and low informational completeness (median score, 1.432; range, 1.000-2.046). Residents' scores increased modestly by one point after viewing (from 13 to 14; p < 0.001). Misinformation was positively correlated with the number of followers (beta coefficient: 0.00002, p < 0.001), video duration (beta coefficient: 0.0042, p < 0.05), and linking ratio (beta coefficient: 0.242, p < 0.05). Conversely, informational completeness was inversely correlated with video duration (beta coefficient: - 0.001121, p < 0.05) and the thumbs-up/view ratio (beta coefficient: - 67.4697, p < 0.05).

conclusionsWhile YouTube® has potential as an accessible educational tool, current video selection offers limited improvement in residents' understanding of tracheal intubation. Our findings highlight the need for greater curation and better-quality control of medical educational content on YouTube® to optimize its effectiveness and provide accurate information. Institutions could play a key role in producing reliable, guideline-based videos that better support learning objectives in anesthesiology training.
