Title: Characteristics and Outcomes of Patients with Pulmonary Acute Respiratory Distress Syndrome Infected with Influenza versus Other Respiratory Viruses

    Snippet: The present study has several limitations. First, this study was conducted at a single center and analyzed data retrospectively, therefore selection bias cannot be excluded. Second, the site obtaining respiratory sample was not the same, therefore, whether respiratory viruses were pathogens cannot be ac-curately distinguished. The miss to detect respiratory viruses by multiplex RT-PCR cannot be ruled out. Third, the change in clinical decision by.....
    Document: The present study has several limitations. First, this study was conducted at a single center and analyzed data retrospectively, therefore selection bias cannot be excluded. Second, the site obtaining respiratory sample was not the same, therefore, whether respiratory viruses were pathogens cannot be ac-curately distinguished. The miss to detect respiratory viruses by multiplex RT-PCR cannot be ruled out. Third, the change in clinical decision by identifying respiratory viruses was not evaluated as in a previous study 5 . Fourth, the prone position was performed in the low proportion of patients with ARDS compared to a recent study 1 .
