TABLE 3.

Multiple logistic regression for 90–day survival: Effects of pre–ECMO PaO2/FiO2–ratio and treatment during different waves of the pandemic

Odds ratio (95% CI) p‐value
PaO2/FiO2 1.015 (0.995, 1.036) 0.157
Wave (first vs. second) 0.634 (0,156, 2.578) 0.524
Wave (first vs. third) 0.328 (0.069, 1.549) 0.159

Note: Multiple logistic regression for the effect of PaO2/FiO2–ratio and treatment during different waves of the pandemic on 90–day survival. For both factors no statistically significant effect was detected in this model. For both factors no statistically significant effect was detected in this model.

Abbreviations: CI, confidence interval; ECMO, extracorporeal membrane oxygenation; FiO2, fraction of inspired oxygen; PaO2, partial pressure of arterial oxygen.
