  1. ATS Anthroposophic Therapeutic Speech, FEV1 forced expiratory volume in 1 s, FVC forced expiratory vital capacity, IQR interquartile range
  2. *Range 5–25, higher scores indicate less severe disease, score >19 indicates well-controlled asthma
  3. Range 1–7, higher scores indicate less impairment
