At the commencement of the study reasons for EN indication
were dysphagia in 86.1% of the patients and oral feeding
refusal in 13.1%. During the course of the study the authors
claim that 13.9% (n=11) of patients resumed oral route, but no
mention was made concerning the group of diseases to which
these patients belonged or how mortality was calculated since
there was a change of intervention – the lack of information
on important aspects of patients’ follow-up is among the
reasons that led to an evaluation of this article as of a weak
methodological quality (Table 1). It is most likely that patients
who refused oral nutrition at the beginning of the study and
the ones who presented mild to moderate degrees of dysphagia
were the ones who resumed oral route.
