Quality assessment and comparison of two- and three-dimensional YouTube videos as additional educational tools for cataract surgery: "METAVERSE".
Article in Irish journal of medical science, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundTo compare the content and quality of 3D YouTube videos with 2Ds as additional educational tools for phacoemulsification surgery.
methodsThis cross-sectional study included 2D and side-by-side 3D phacoemulsification videos found on YouTube by searching for "phacoemulsification," "phaco," and "cataract." Data was collected on video length (min), time since upload (days), number of views, likes, dislikes, cataract type, chop technique, and visualization system. Video popularity and interaction were calculated by video power index, interaction index, and viewing rate. Two senior ophthalmologists (SOs) and two ophthalmology residents (ORs) evaluated videos using the DISCERN, global quality score (GQS), and usefulness scoring systems. Inter-rater reliability was assessed using intra-class correlation coefficient (ICC).
resultsA total of 457 videos were screened, with 85 in 2D and 85 in 3D deemed appropriate for analysis. 2D videos received significantly more views, likes, dislikes, days since upload, video power index, and viewing rate than 3Ds (p < 0.001). Video length and interaction index in 3D videos were significantly greater than in 2Ds (p < 0.001). All video scoring systems revealed that 3D videos outperformed 2Ds in ORs (p < 0.05). ICC confirmed good inter-rater reliability agreement even at the lowest value (SOs: 0.924, 95% CI, 0.910-0.937; ORs: 0.892, 95% CI, 0.878-0.908).
conclusions3D YouTube videos as additional educational tools could help not only SOs but also ORs fully comprehend the breadth and depth of ocular surgeries, particularly phacoemulsification, by improving depth perception. They can also be used to review previously learned procedures, observe new ones, and recall old ones.
