  1. aAsthma was defined as fulfilling at least 2 of 3 criteria: symptoms of wheeze and/or breathing difficulties in the preceding 12 months, ever doctor’s diagnosis of asthma and/or use of asthma medication occasionally or regularly in the preceding 12 months
  2. bp values obtained using chi-squared and Fisher’s exact tests to analyse differences between the distribution of EQ-5D descriptive system values between females and males with no asthma at the 24-year follow-up
  3. cp values obtained using Fisher’s exact test to analyse differences between the distribution of EQ-5D descriptive system values between females and males with asthma at the 24-year follow-up
