  • N/WMA indicates Navajo/White Mountain Apache; SaO2, oxygen saturation; NS, not statistically significant. Non–high-risk children had no underlying condition that might predispose to severe RSV disease (as defined in the text and Table 1) and were not premature (<36 weeks’ gestation). Data from JHH was previously published20 and was reanalyzed to exclude children younger than 24 months.
