Smart glasses integrated with a wireless ultrasound system for radial artery catheterization in elderly patients: a randomized controlled trial.

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
Background: Radial artery catheterization can be challenging in elderly patients. The clinical value of integrated system combining a wireless ultrasound probe and smart glasses remains unclear. This study evaluated whether this approach improves first puncture success compared with conventional ultrasound guidance. Materials and methods: This prospective randomized controlled trial enrolled 194 patients aged ≥65 years with American Society of Anesthesiologists physical status I-III who were scheduled for elective surgery requiring radial artery catheterization. Patients were randomly assigned to the smart glasses group or conventional ultrasound group in a 1:1 ratio. The primary outcome was the first puncture success rate. Secondary outcomes included procedure-related behavioral indicators of hand-eye coordination, procedure time, and operator satisfaction. Results: A total of 194 patients were analyzed. The first puncture success rate was significantly higher in the smart glasses group than in the ultrasound group [88/97, 90.72% vs. 66/97, 68.04%; Conclusion: Compared with conventional ultrasound guidance, integrated wireless ultrasound and smart glasses system improved the first puncture success rate of radial artery catheterization in elderly patients and enhanced procedure-related behavioral indicators associated with hand-eye coordination, including head rotations, ultrasound probe repositioning, and needle angle adjustments. This approach also shortened procedure time and improved operator satisfaction.
