  1. All 235 infants included in the RSV-NPA study are shown in this table. Physician diagnosed post-bronchiolitis wheeze (PBW) in the first year after infection was not known in fifty infants and these infants were left out of PBW analyses. No statistical significant differences are present in the general characteristics of the infants with or without physician diagnosed PBW, or in the infants missing follow-up data (n = 50). 1Ranges and percentages are written between parentheses. 2A semiquantitative parental score for atopy was used [41]. One point was added to score for presence of each atopic symptom (eczema, hay fever, bronchitis, asthma, and food allergy) in both parents, with a minimum score of 0 and a maximum score of 10.
