Comparison of the vertical angle errors at the first and second anchor spots. In the phantom-based anchor insertion experiments, the anchoring angle error in the expert group significantly decreased when the proposed navigation system was used (*). The mean for each participant, including those in the expert and novice groups, shows a significant difference between the conventional and proposed navigation systems in terms of anchoring angle error (**)
