Delayed Retention of Technical Surgical Skills Following Virtual, Augmented, and Mixed-Reality Simulation: A Systematic Review and Meta-analysis

Background: Extended-reality simulation is widely used for technical surgical training, yet immediate gains do not establish that skills persist once practice stops. Objective: To characterize delayed technical-skill outcomes after virtual, augmented, or mixed-reality training and estimate the comparative effect at the...
