  • PSI: pneumonia severity index; CURB-65: confusion, urea >7 mmol·L−1, respiratory rate ≥30 breaths·min−1, blood pressure <90 mmHg (systolic) ≤60 mmHg (diastolic), age ≥65 years; ICU: intensive care unit; #: Hosmer–Lemeshow goodness-of-fit test, p=0.32; : the p-value corresponds to differences between the three groups (not ventilated, non-invasive or invasive).
