a
Steps adequately seen on video review but not adequately described in the narrative operative note.
b
Steps adequately described in the operative note but not adequately seen on video review.
c
The column labeled “described but not seen” was not adjusted with audio; the 2 columns will therefore stay similar.
d
Comparison of the combined discrepancies per step without audio adjustment vs with audio adjustment. Values are Bonferroni corrected.
e
Comparison of the combined discrepancies in total without audio adjustment vs with audio adjustment. Value is per the Wilcoxon signed rank test and is Bonferroni corrected.
