A Study on the Epidemiological-Molecular Role of <i>Staphylococcus aureus</i> Strains in the Development of Ventilator-Associated Pneumonia in a Tertiary Hospital in Brazil.

Statistical Analysis Poisson regression of host and microbiological factors was performed to evaluate their relationship with the development of VAP and death, using backward selection (the first model included all variables, and the multivariate model included variables with p > 0.1, removing the variable with the highest p -value at each step and including only those with p < 0.1, i.e., significant, and marginally significant variables).
