Since this may be associated to the small sample sizes or to methodological quality, it is important to clarify that this does not mean that the review was poorly conducted. Only 15 articles concerning ELISA with monoclonal antibodies were included due to the small amount of literature written on the topic.
Esta circunstancia no necesariamente implica limitaciones de la presente revisión ya que el número de artículos al respecto no es superior a 15, dado que es escasa la literatura sobre antígenos fecales utilizando anticuerpos monoclonales.
