Data analysis
Statistical analysis was performed using StataV13.1
(StataCorp LP, College Station,Texas, USA). Categorical
variables were compared between groups using Pearson’s
chi-squared test. Differences in groups were analysed using
the two-sample Wilcoxon rank-sum test (Mann-Whitney
U-test). A P-value of less than 0.05 was considered to
indicate statistical significance
groups: the ‘pain’ group and the ‘no pain’ group. Using the
variables in the registry, the groups were analysed from two
perspectives: antibiotic treatment before entering the study
and during the study period, and compression therapy during
the study period.
