Methods	DESIGN: Randomised controlled trial ALLOCATION: By third party using sealed opaque envelopes. BLINDING PROCEDURES: Data entry blinded SAMPLE CALCULATION: Yes DURATION: Up to 12 months FOLLOW‐UP: Weekly urinalysis WITHDRAWALS/DROPOUTS: None ITT: Yes GEOGRAPHICAL LOCATION: Canada SETTING: Rehabilitation Hospital
Participants	N = 36 DIAGNOSIS: Neurogenic bladder due to recent high spinal cord injury; neurogenic bladder. ELIGIBLE: 50 ENROLLED: 36 COMPLETED: 36 AGE: Adults GENDER: 28 male, 8 female
Interventions	Sterile technique vs clean technique Sterile single‐use PVC catheter with sterile technique or sterile single‐use PVC catheter with clean technique (clean gloves, clean container, non‐sterile wipes for cleansing pre catheterisation) (uncoated, non‐lubricated both arms)
Outcomes	Days to onset of symptomatic UTI
Notes	UTI defined as >= 10x5 CFU/mL, pyuria + accompanying symptoms; no difference between groups.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	"Computer generated random numbers"
Allocation concealment (selection bias)	Low risk	"Sealed brown envelopes"
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	"It was not possible to blind nursing staff"
Blinding of outcome assessment (detection bias) All outcomes	Low risk	"laboratory was blinded to subject allocation"
Incomplete outcome data (attrition bias) All outcomes	Low risk	No incomplete data
