The PARADIGM Study: Procedural Augmented Reality Assessment in a 3-Dimensional Image-Guided Modality
Authors' conclusion
The CommandEP system improved physicians’ ability to navigate accuracy, reduced the number of communications, increased the quality of communications, and had high usability.

Accuracy pre- versus postcontact force (subanalysis)
- No difference in accuracy
- P = ns
Low- and high-quality communications (subanalysis)
- Slight reduction in both low- and high-quality communications
- P = ns
