Comparison between the No and Any complications group have been made using the Mann–Whitney test, all other comparisons between subgroups were assessed by the Kruskal-Wallis test using the Conover post-hoc analysis.
Bold type shows statistical significance against the patients without complications.
Negative number in additional costs: decrease in costs as compared to patients without complication.
Abbreviations: CRBSI – Catheter related blood stream infection, UTI – Urinary tract infection (including asymptomatic bacteriuria).
