IC‐treated children (5 wheeze, 9 respiratory symptoms other than wheeze, 4 without chronic symptoms) had lower median (interquartile range) EBT levels than IC‐untreated children (n = 280) [EBT: 31.7 (30.1–32.5) vs. 32.6 (31.4–33.4), <italic>P</italic> = 0.027]. Duplicate EBT measurements were highly reproducible (ICC = 0.94).
