  • a N = 609 (univariate) and N = 589 (multivariate). Death number (percent) in room air (RA) and oxygen (O2) groups and OR for various adverse events when comparing the room air group versus the oxygen group. The multivariate analysis is adjusted for gender, gestational age, and birth weight. The 73 infants in the room air group that had been switched to oxygen after 90 seconds because of so-called resuscitation failure (see text) were analyzed in the room air group.

  • F3-b Compared with children followed for 28 days.N = 561 (univariate) and N = 543 (multivariate). At 28 days, 21 infants were lost to follow-up in the room air group and 27 infants in the oxygen group.
