No difference in total procedure time when using stereotactic navigation versus no navigation. The plausible distributions of mean values consistent with the data are shown for the total procedure time 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 procedure time is nearly identical for both groups: A 69 min with stereotactic navigation and B 68 min without navigation. The average standard deviations are also nearly identical E. C The difference of means centers at approximately zero with 94.7% of the 95% HDI within the ROPE, indicating no difference in total procedure time. D The effect size also centers effectively at zero and completely overlaps the ROPE, supporting no difference in total procedure time when using stereotactic navigation or not
