Table 5. Acute and chronic comorbidities in patients with community-acquired compared to nosocomial-acquired pneumonia caused by Pseudomonas aeruginosa.

Comorbidities were only considered if they were more than 10% in one of the groups, even if they were less than 10% in the other group. Note: Significant P values are shown in bold.
