In our study “Adequacy of enteral nutrition support in intensive care units does not affect the short- and long-term prognosis of mechanically ventilated patients: a pilot study”() the sample size was calculated to assess the short-term effects, and in this sense, it is not a pilot study. However, we had no information available in the literature, much less in the Brazilian settings about what the sample size would be for a long-term study. Thus, it was considered a pilot study, which allowed us to estimate the magnitude of losses and deaths and to calculate the sample.())
