Statistical charts and scatter plots for the two operator habits show that Habit 2 has greater deviation distances and guide oscillation compared to Habit 1.Fig. A corresponds to the Inclined Plane Group, Fig. B to the Plaster-Fixed Vertebra Group, Fig. C to the frontal view, and Fig. D to the lateral view. The ellipses in Figs. C and D encompass 95% of the coordinates. In the present Figs. and subsequent images, H1/H2 denote Habit 1/Habit 2, respectively. The numbers 410/500/600 represent robotic arm lengths of 410 mm, 500 mm, and 600 mm, respectively. The numbers 1/5 denote guide-to-bone surface distances of 1 cm and 5 cm, respectively. Ca/Si denote the Plaster-Fixed Vertebra Group/Silicone-Fixed Vertebra Group. In the significance analysis, n.s. indicates P > 0.05, * indicates P ≤ 0.05, ** indicates P ≤ 0.01, and *** indicates P ≤ 0.001
