Methods	Method of randomisation unclear Blinding unclear (traditional liquid diet with swallowing therapy vs control)
Participants	1 centre in China 64 participants; timing unclear All dysphagia as defined by Watian Swallow Test
Interventions	R1: enteral nutrition agent with thickener and swallowing therapy (n = 18) R2: traditional liquid diet and swallowing therapy (n = 22). This data set was split (n= 11)* C: liquid diet only and no swallowing therapy (n = 24) (R1 and R2 had NGTs for an uncertain amount of time) *Compared in data set 1
Outcomes	Length of stay, pneumonia rates, nutritional measures, resolution of dysphagia (swallow test grade)
Notes	Exclusions: terminal illness, organ failure Unclear if any blinding of interventions or outcomes occurred
