Spearman's coefficient of correlation between lung function variables and different measures of oxygenation ability
| Functional residual capacity | Compliance | Specific conductance | Gas-mixing efficiency | |
|---|---|---|---|---|
| Average AaDO2 first month | −0.40 p=0.01 | −0.19 p=0.27 | 0.32 p=0.06 | −0.12 p=0.48 |
| AaDO2 at 36 weeks PMA | −0.28 p=0.09 | −0.39 p=0.02 | 0.41 p=0.01 | 0.06 p=0.71 |
| Duration of supplemented oxygen | −0.32 p=0.055 | −0.36 p=0.03 | 0.50 p=0.002 | 0.12 p=0.46 |
| Gestational age at birth | 0.31 p=0.07 | −0.06 p=0.74 | −0.44 p=0.008 | −0.06 p=0.71 |
