Use of smart glasses imaging for interscalene brachial plexus block: a randomised clinical trial.
Trial report in British journal of anaesthesia, 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
backgroundSmart glasses can provide real-time ultrasonographic images without additional head-eye movement. We investigated whether smart glasses combined with ultrasonography could improve interscalene brachial plexus block (ISB) procedural efficiency.
methodsThis prospective, randomised trial enrolled 151 patients undergoing upper limb surgery requiring interscalene brachial plexus block. Four anaesthesiologists received standardised training in smart glasses-assisted (smart glasses group) or conventional (control group) ultrasound guidance. The primary outcome was total procedure time.
resultsFive participants were excluded, and 146 participants were included in the analysis. The total puncture time was shorter in the smart glasses group compared with the control group (124.0 [98.0-155.5 ] s vs 153.0 [123.0-197.5] s; P<0.001). In addition, the ultrasound probe imaging time was better in the smart glasses group than in the control group (19.0 [13.5-30.0] s vs 31.0 [20.0-51.0 ] s; P<0.001), and the period from the first skin puncture to reaching the target area was also shorter (16.0 [12.5-24.5] s vs 26.0 [18.5-33.5] s; P<0.001). Hand-eye coordination was significantly better in the smart glasses group compared with the control group, which included fewer operator head movements (1.0 [1.0-2.0] vs 5.0 [3.0-8.0]; P<0.001); more consistent needle redirections (3.00 [2.0-3.0] vs 3.0 [2.0-4.0]; P=0.004). Pain scores remained similarly low in both groups, with no significant differences in adverse event rates. Ergonomic satisfaction scores (rated 4 or 5) were higher in the smart glasses group (56.2% [41/73] vs 24.7% [18/73]; P<0.001).
conclusionsSmart glasses reduced the procedure time for experienced anaesthetists performing interscalene brachial plexus block compared with the control group, and improved their hand-eye coordination and satisfaction. CLINICAL
