| Notes | ||
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement | 
| Random sequence generation (selection bias) | Unclear risk | Not stated | 
| Allocation concealment (selection bias) | Unclear risk | Not stated | 
| Blinding of participants and personnel (performance bias) All outcomes | Low risk | No blinding, but the review authors judge that the outcome and outcome measurement are not likely to be influenced by lack of blinding. | 
| Blinding of outcome assessment (detection bias) All outcomes | Low risk | Participant‐reported outcome, but risk of detection bias considered low as cross‐over trial | 
| Incomplete outcome data (attrition bias) All outcomes | Unclear risk | Missing outcome data from 2 participants ‐ withdrawals described as catheter‐related reasons, but type of catheter not specified |
