Methods	Method of randomisation unclear: participants from both the lateral medullary infarction (LMI) group and the other brainstem infarction group were each randomly classified into 2 groups ‐ to receive real or sham repetitive transcranial magnetic stimulation Blinded primary outcome assessment Baseline prognostic factors balanced between treatment groups
Participants	1 centre in Egypt Total of 22 participants with hemispheric stroke split into having lateral medullary infarction or other brainstem infarction Mean age 58 years
Interventions	Rx: repetitive transcranial magnetic stimulation of the affected motor cortex (n = 11) C: sham stimulation (n = 11)
Outcomes	Primary outcome: score on the dysphagia rating scale Secondary outcomes: motor power of hand grip, BI, NIHSS
Notes	Exclusion: head injury or neurological disease other than stroke, unstable cardiac dysrhythmia, fever, infection, hyperglycaemia, epilepsy, prior administration of tranquilliser
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Method of randomisation unclear
Allocation concealment (selection bias)	Unclear risk	Unclear
Blinding (performance bias and detection bias) All outcomes	Unclear risk	Unclear
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Unclear
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Blinded outcome assessment
Incomplete outcome data (attrition bias) All outcomes	Low risk	All participants apart from 2 in the sham treatment group who died completed the trial and follow‐up periods
Selective reporting (reporting bias)	Low risk	All outcomes reported
Other bias	Low risk	None identified
