Data are presented as % (95% confidence interval). ^#: differences for group which changed from obese to not obese not shown due to wide confidence intervals; ^¶: adjusted additionally for centre and age group (wheeze) and country (wheeze without a cold); ⁺: p-values for overall differences between four groups defined by obesity status.
