Virtual Reality Distraction vs Nitrous Oxide for Reducing Anxiety and Injection Pain.
Trial report in Anesthesia progress, 2025. 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
Objective: The purpose of this study was to compare nitrous oxide (N2O) vs virtual reality (VR) as methods for reducing pain and anxiety during a dental injection. The primary objectives were to assess acute changes in stress responses by comparing salivary cortisol levels between the 2 groups and differences in injection pain scores. Methods: A total of 132 female subjects serving as their own control received maxillary lateral incisor infiltration injections with the use of either N2O or a VR headset during separate appointments spaced at least 2 weeks apart. Salivary cortisol samples were collected at 6 times throughout each appointment. Pain scores for needle insertion and solution deposition were recorded. Data were analyzed statistically using Wald and paired t tests. Results: N2O significantly lowered salivary cortisol concentrations and subsequent physiologic anxiety as compared with VR (P = .0089). However, no significant differences in needle insertion or solution deposition pain scores were found. Conclusion: Although VR and N2O may be comparable in terms of perceived pain reduction, N2O was a more effective method than VR for physiologic analgesia and anxiolysis.
