IQR = interquartile range; -Wallis test; significant differences in pairwise comparisons between ASA categories with Mann–Whitney tests using Bonferroni-corrected values: In pre phase I versus III (), I versus IV (), II versus IV (), and III versus IV (); in intra phase I versus III (), I versus IV (), II versus III (), II versus IV (), andn III versus IV (); in post phase I versus III (), I versus IV (), II versus III (), and II versus IV (). Three patients in ASA category V were excluded from the analysis. ASA category VI did not appear in our data.
