| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | No information given on method of randomisation |
| Allocation concealment (selection bias) | Unclear risk | No information given on method of allocation concealment |
| Blinding of participants | High risk | No information given. As suprapubic vs indwelling can assume that blinding did not occur |
| Blinding of personnel | High risk | No information given. As suprapubic vs indwelling can assume that blinding did not occur |
| Blinding of microbiological outcome assessment | Unclear risk | No definition given for symptomatic UTI so do not know if assessed by microbiologist from urine culture, or assessed by clinician based on symptoms |
| Blinding of outcome assessment (detection bias) All outcomes | Unclear risk | No information given |
| Incomplete outcome data (attrition bias) All outcomes | Low risk | 60 participants randomised (suprapubic 24, urethral 36). No dropouts |
| Selective reporting (reporting bias) | Unclear risk | Outcomes that were to be reported not stated. Unable to access protocol so some uncertainty surrounding reporting bias |
| Other bias | Low risk | Appears to be free of other sources of bias |
