| Variables |

||
|---|---|---|---|---|
| Adjusted OR | 95% CI | Adjusted OR | 95% CI | |
| Gestational age | 1.54/week | 1.45–1.64 | 1.00/week | 1.00–1.07 |
| Birth weight* | 1.22/100g | 1.16–1.28 | 0.94/100g | 0.92–0.97 |
| 1 min Apgar score | 1.16/point | 1.05–1.28 | 1.12/point | 1.02–1.2 |
| Patent ductus arteriosus | 3.5 | 2.1–6.0 | – | – |
| Pneumothorax | 9.4 | 3.6–24.8 | 5.8 | 2.5–13.7 |
| Neonatal pneumonia/sepsis | 1.9 | 1.1–3.2 | – | – |
*
The adjusted OR for birth weight was obtained by running the model a second time in parallel with all the other variables, with the exception of gestational age, to avoid collinearity between the two variables. Patent ductus arteriosus and neonatal pneumonia/sepsis were not included in the RDS model because both diagnoses were made during or after the development of the RDS
