No difference in time to target probe placement when using stereotactic navigation versus no navigation. The plausible distributions of mean values consistent with the data are shown for the time required for target probe placement A with stereotactic navigation and B without navigation assistance. C shows the pairwise differences of these sampled means and D indicates a strength of the effect accounting for the amount of variability within the groups. E summarizes the average values of the mean and standard deviation distributions consistent with the data. The mean time to target placement is very similar for both groups: A 49 min with stereotactic navigation and B 53 min without navigation with nearly equivalent standard deviations E. C The difference of means centers close to zero with 90.1% of the 95% HDI within the ROPE, indicating no difference in time to target probe positioning. D The effect size also centers at approximately zero and completely overlaps the ROPE, supporting no difference in time to target probe placement
