|Variable||Coefficient (β)||SE||p value||OR (95% CI)|
|O2 saturation||–0.55||0.24||0.02||0.58 (0.36–0.92)|
*ICU, intensive care unit; OR, odds ratio; CI, confidence intervals; O2 saturation, oxygen saturation. Variables included in regression analysis: age <5 y, number of high-risk conditions per Centers for Disease Control and Prevention, history of prematurity, congenital heart disease or pulmonary disease, the presence of dyspnea, tachypnea, O2 saturation, and acute renal failure. Chest radiograph infiltrate was not included in the model because only half of the study cohort received a chest radiograph. This model was well-fitted with a Hosmer–Lemeshow statistic of 0.923.
