Abbreviations: BSS, Bronchiolitis Severity Score; SD, standard deviation; SE, standard error.
*BSS was measured on a 0–12 scale, 12 represents the most severe score.
†Adjusted for age at enrollment and for infant's formula consumption. Reported with mean (SE): presented as SE and not SD because data are adjusted for age.
‡Adjusted for birth length and for infant's formula consumption. Reported with mean (SE): presented as SE and not SD because data are adjusted for birth length.
