Subgroup analyses to identify the source of significance within the drilling direction (left) and guidance technique (right) subgroups. The mean deviation angles (value along y-axis, expressed in degrees, error bars representing the 95% confidence interval) within each drilling direction (perpendicular, oblique) and guidance technique (freehand, proprioception, AR) subgroup were compared for significance. Each of these analyses was performed only within their respective subgroup. FH = freehand; PR = proprioception; AR = augmented reality; * = p < 0.05; *** = p < 0.001.
