Augmented reality in clinical skills simulation: usability and feasibility of smart glasses in a simulated environment.
Article in Acta cirurgica brasileira, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo assess the usability and feasibility of augmented-reality smart glasses during simulated pediatric bladder catheterization with real-time remote specialist guidance.
methodsThirty-five critical-care graduate healthcare professionals simulated pediatric bladder catheterization on a manikin using Vuzix M400 glasses via telemedicine. After brief familiarization, participants completed a seven-item Likert (0-7) questionnaire covering ease of use, procedural understanding, confidence/efficiency, comfort, and global acceptance. We analyzed descriptive statistics, internal consistency (Cronbach's α), and item-domain coherence. A conceptual diagram and synthesis table complemented quantitative data.
resultsAugmented-reality-guided training showed generally favorable usability perceptions. Median scores ranged 3.5-5, with strongest ratings for observation support, image quality, procedural understanding, and intention to recommend. Comfort and efficiency scored lower (median = 3.5), indicating more neutral perceptions. The instrument showed high internal consistency (α = 0.97), although this may reflect item redundancy, and item-domain alignment provided a descriptive representation of the conceptual model.
conclusionThese findings suggest that augmented-reality smart glasses are feasible and generally well accepted for simulated remotely guided training. Further controlled studies with objective performance measures are needed.
