Risk of bias table for intervention studies (randomized controlled trials; based on Cochrane risk of bias tool and suggestions by the CLARITY Group at McMaster University)

Study reference (first author, publication year)	Was the allocation sequence adequately generated? Definitely yes Probably yes Probably no Definitely no	Was the allocation adequately concealed? Definitely yes Probably yes Probably no Definitely no	Blinding: Was knowledge of the allocated interventions adequately prevented? Were patients blinded? Were healthcare providers blinded? Were data collectors blinded? Were outcome assessors blinded? Were data analysts blinded? Definitely yes Probably yes Probably no Definitely no	Was loss to follow-up (missing outcome data) infrequent? Definitely yes Probably yes Probably no Definitely no	Are reports of the study free of selective outcome reporting? Definitely yes Probably yes Probably no Definitely no	Was the study apparently free of other problems that could put it at a risk of bias? Definitely yes Probably yes Probably no Definitely no	Overall risk of bias If applicable/necessary, per outcome measure LOW Some concerns HIGH
Atılgan, 2020	Definitely yes Reason: computer-generated randomization was used.	Definitely yes Reason: allocation group was kept in closed envelope.	No information Reason: not reported.	Definitely yes Reason: no loss to follow up.	Definitely yes Reason: all relevant outcomes were reported.	Definitely yes Reason: no other problems noted.	LOW (no information on blinding provided but this has probably no effect on the outcome measure bacteriuria).
Igbodike, 2021	Definitely yes Reason: permutation blocks (blocks of 4, allocation ratio 1:1) with software accessible online.	Definitely yes Reason: consecutively numbered opaque wrapped papers in brown envelopes.	Definitely no Reason: single blinded trial. Patients and surgeons not blinded. Outcome assessors and medical laboratory were blinded.	Definitely yes Reason: no loss to follow up.	Definitely yes Reason: all relevant outcomes were reported.	Definitely yes Reason: no other problems noted.	LOW (patients and surgeons not blinded but this has probably no effect on the outcome measure bacteriuria).
