Data were shown as median (min-max). The comparisons between pre- and post-op measurements within each group, Wilcoxon sign rank test, according to the Bonferroni Correction P < 0.025 was considered as statistically significant. The comparisons between control and study groups, Mann Whitney U test, according to the Bonferroni Correction P < 0.025 was considered as statistically significant except for the comparisons at the last column.
