a decreasing trendp = 0.02
A case-to-case analysis revealed a decreasing trend in the operative time (r = -0.7, p = 0.02) and CT radiation exposure (r = -0.7, p = 0.02) over time.
A case-to-case analysis revealed a decreasing trend in the operative time (r = -0.7, p = 0.02) and CT radiation exposure (r = -0.7, p = 0.02) over time.
Subanalyses of the robot time, screw fixation time, and time per screw showed decreases; however, the correlation coefficient did not reach statistical significance (r = -0.46, p = 0.18; r = -0.48, p = 0.17; and r = -0.58, p = 0.1, respectively).
