3. Figure 2
Scatter plot of performance based on prior experience for 4 study steps of RARP. a, total task completion time as function of prior surgeon experience (console cases). b, instrument path distance of all robotic arms excluding camera. c, average instrument velocity of dominant instrument. Number of cases needed to improve by 50% or 75% in previously mentioned metrics did not differ statistically among 4 steps (p >0.05).

5. Figure 4
Ratio of nondominant-to-dominant hand use for instrument path distance, instrument moving time and average instrument velocity. Asterisk indicates p <0.05. During dissection tasks (BM, SVD, RLD) expert surgeons used dominant hand more compared to novices. There was no difference in degree of bimanual dexterity during AA.
