Study	Reason for exclusion
Abdel Azim 2018	Wrong population: includes only patients on HD by non‐tunnelled catheters
Bosma 2010	Wrong intervention: biofilm prevention rather than treatment of catheter infection
Dahlberg 1986	Wrong population, methods and intervention: study involved 3 different groups with randomised and non‐randomised patients and compared incidence of CRBSI in long‐term versus short‐term dialysis catheters rather than the intervention options for its treatment
ELVIS 2015	Wrong intervention: prevention rather than treatment of catheter infection, also compared dysfunction
Harris 1997	Wrong intervention: study assessed the prevention of infection and dysfunction for a specific catheter rather than treatment of catheter infection
Hymes 2017	Wrong intervention: prevention rather than treatment of catheter infection
Levin 1989	Wrong intervention: prevention rather than treatment of catheter infection
NCT00108433	Study abandoned and not published with the wrong population and intervention: includes short‐term catheters and compared two different systemic antibiotics alone without catheter management
NCT01483872	Study abandoned early due to inadequate enrolment
NCT02040818	Study abandoned early due to inadequate enrolment
Oliver 2007	Wrong intervention: use of fibrin sheath disruption for prevention rather than treatment of catheter infection
Rosenblum 2014	Wrong intervention: prevention rather than treatment of catheter infection
Zwiech 2016	Wrong intervention: use of taurolidine‐citrate‐heparin lock solution for prevention rather than treatment of catheter infection

CRBSI ‐ catheter‐related bloodstream infection; HD ‐ haemodialysis
