Methods	Randomisation via computer‐generated block randomisation Blinding unclear Analysis by ITT unclear Prognostic baseline factors between treatment groups similar
Participants	1 centre in Korea 57 participants with dysphagic stroke within 10 days of onset (men 42, women 15) Mean age 65 years
Interventions	Rx: NMES combined with traditional dysphagia therapy (n = 31) C: traditional dysphagia therapy only (n = 26) 5 days per week for 3 weeks
Outcomes	Swallowing function, Functional Oral Intake Scale
Notes	Exclusion: presence of dysphagia before stroke, previous history, unstable cardiopulmonary status, serious psychological disorder or epilepsy, tumour or radiotherapy of the head and neck region, swallowing therapy before participation in the present study, unstable medical conditions that may interfere with VFSS
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computer‐generated block randomisation
Allocation concealment (selection bias)	Unclear risk	Not reported
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	Unclear risk	Unclear
Incomplete outcome data (attrition bias) All outcomes	Low risk	All participants appeared to have been followed up at 12 weeks
Selective reporting (reporting bias)	Low risk	All outcomes reported
Other bias	Low risk	None identified
