“… 30 , 31 , 32 , 33 There is, however, a significant selection bias in studies using instrumental assessment of swallowing in acute stroke patients, which can influence not only the prevalence of dysphagia and aspiration risk but also the specific findings of swallowing impairment. 5 Prolonged intubation, reduced vigilance, non‐compliance, medical contraindications to FEES (such as respiratory instability, cardiocirculatory instability, impending cerebral herniation and active upper respiratory tract bleeding), 34 early death or palliative care are not rare in acute stroke patients, limit the instrumental assessment of swallowing, and explain why our final study population had less severe strokes and less frequently had complications such as sICH and stroke‐associated pneumonia. Therefore, we hypothesize that the prevalence of early dysphagia in non‐selected ischaemic stroke patients undergoing MT is even higher than the one we found.…”
