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
Introduction: Distractions and interruptions may interfere with concentration, working memory, and timely decision-making. This study aimed to analyze the visual attention patterns of medical interns during the management of a multiple-trauma patient in a realistic virtual reality (VR) emergency scenario using eye-tracking technology integrated into VR simulation. Methods: This cross-sectional simulation-based study was conducted among 15 medical interns at Tehran University of Medical Sciences. Participants were exposed to a 242-second high-fidelity VR trauma scenario representing a crowded ED with multiple environmental distractions and interruptions. Eye-tracking data were collected using the HTC Vive Pro Eye headset. The scenario was divided into four predefined temporal intervals. Areas of interest (AOIs) were defined and classified as relevant (main patient, key treatment team members, and essential equipment) or distractors (nonessential environmental and emotional stimuli). Main outcome measures included cumulative gaze time on relevant and distractor AOIs, gaze time outside defined AOIs, and the Relevant/Distractor ratio. Results: A total of 253,075 gaze samples were obtained, with a mean of 16,871.7 ± 2,097.0 samples per participant. The mean duration of valid eye-tracking data was 238.5 ± 12.3 seconds per participant, corresponding to approximately 98.6% of the total scenario time. Across all intervals, gaze was predominantly directed toward relevant AOIs, and this pattern became progressively stronger over time. The Relevant/Distractor ratio increased from 3.41 ± 1.58 in the initial interval to 27.60 ± 26.12 in the final interval, while attention to distractor AOIs decreased from 19.2% to 4.7%. Spatially, the head and face of the main injured patient, the emergency medicine resident, and the patient monitor consistently attracted the greatest attention. Conclusion: Medical interns progressively adopted a more structured and goal-directed visual attention strategy, increasingly prioritizing vital clinical information over distracting stimuli. VR-based eye tracking appears to be a feasible and informative tool for assessing attentional behavior and may support targeted educational interventions in trauma training.
