| Risk of bias |
| Bias |
Authors' judgement |
Support for judgement |
| Random sequence generation (selection bias) |
Low risk |
Randomisation by sequentially numbered sealed envelopes |
| Allocation concealment (selection bias) |
Low risk |
Allocation concealed by sealed envelopes |
| Blinding (performance bias and detection bias)
All outcomes |
Low risk |
Participant blinded; outcome assessor blinded |
| Blinding of participants and personnel (performance bias)
All outcomes |
Low risk |
Participant blinded |
| Blinding of outcome assessment (detection bias)
All outcomes |
Low risk |
Outcome assessor blinded ‐ measures evaluated by a trained neurologist who was blinded to participants' group allocation throughout |
| Incomplete outcome data (attrition bias)
All outcomes |
Low risk |
2 participants lost to follow‐up |
| Selective reporting (reporting bias) |
Low risk |
Only NIHSS not recorded at the end; all other measures reported on for all 3 time points |
| Other bias |
