| Characteristic | PE (n = 167) | CAP (n = 58) | ARTI (n = 63) | p-value |
|---|---|---|---|---|
| Gender, male (%) | 84 (50.3) | 31 (53.4) | 40 (63.5) | 0.358 |

| Hospital stay (days), median (range) | 5.31 (0–8) | 7.08 (0–34) | 1.51 (0–29) | <0.0001 |
| 30 day mortality, n (%) | 7 (4.2) | 16 (27.6) | 9 (14.3) | <0.0001 |
| CRP (mg/l), median (range) | 67.3 (4–412) | 88.9 (12–417) | 68.9(9–284) | 0.322 |
