Influence of comorbidities and long-standing diagnoses on the outcome of mechanical ventilation and death in seasonal and pandemic influenza.

<p>Logistic regression was used to estimate the influence of certain variables, such as age, gender and comorbidities on outcomes of mechanical ventilation and death. (A) Influence of comorbidities on fatal outcomes in seasonal influenza. ORs greater than 1 mean that the analysed factor occurred favourably in fatal cases. (B) Influence of comorbidities on fatal outcomes in pandemic influenza. ORs greater than 1 mean that the analysed factor occurred favourably in fatal cases. (C) Influence of comorbidities on the outcome of MV in seasonal influenza. ORs greater than 1 mean that the analysed factor occurred favourably in MV cases. (D) Influence of comorbidities on the outcome of MV in pandemic influenza. ORs greater than 1 mean that the analysed factor occurred favourably in MV cases.
