Using virtual reality or slideshow to teach ultrasound-guided lumbar puncture: immersion increases fun.
Trial report in BMC medical education, 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
purposeVirtual reality (VR) has been used to teach a variety of procedural skills in medical education. Ultrasound-guided lumbar puncture (USG LP) shows promise to increase procedural success in adults and pediatric patients without impactfully increasing procedure duration. We explore engagement, enjoyment, and procedure performance of medical students learning this skill from a pre-recorded slideshow or VR lecture.
methodWe recorded a slideshow lecture and a virtual reality lecture teaching background knowledge and technique necessary for performing USG LPs. Medical Students were randomized to participate in one of these modalities and filled out a survey on their experience. They were then timed and graded on their performance of the procedure on an LP task trainer.
resultsFifty-five medical students (27 slideshow, 28 VR) at two universities were involved in the study. Level of fun was rated higher in the VR group (4.5 [4.0, 5.0] vs. 4.0 [3.0, 4.0], p = 0.0002) along with perceived effectiveness of the lectures (4.0 [4.0, 5.0] vs. 4.0 [4.0, 4.0], p = 0.0265) and level of enjoyment (5.0 [4.0, 5.0] vs. 4.0 [4.0, 5.0], p = 0.0232), while level of boredom (2.0 [1.0, 3.0] vs. 3.0 [2.0, 4.0], p = 0.0308) was rated lower in VR. There was no statistically significant difference in simulated cerebrospinal (CSF) acquisition, LP checklist score, or procedure duration. VR participants reported more side effects and technology issues.
conclusionsVirtual reality is perceived as more fun, more effective, and a more enjoyable training modality with increased learner engagement compared to slideshow lectures when learning ultrasound guided-lumbar puncture. Procedural results were similar between the learning modalities, though there is a learning curve to understand and troubleshoot technological issues that may arise when utilizing VR.
