| Outcome variable | Rib fixation for multiple rib fractures | |||||
|---|---|---|---|---|---|---|
| Median (IQR) | δ | 95% CI | SE | p value | ||
| Surgery | Non-operative | |||||
| Duration of ICU stay in days | 0 (0–11) | 1 (0–2) | 1.6 | − 3.5 to 6.7 | 2.600 | 0.530 |
| Duration of IMV in days | 0 (0–9) | 0 (0–1) | 2.4 | − 2.8 to 7.6 | 2.637 | 0.365 |

SE standard error; OR odds ratio; ICU intensive care unit; IMV invasive mechanical ventilation; CI confidence interval; IQR interquartile range; NA no answer
δ indicates the difference in mean outcome value between rib fixation and nonoperative treatment
