  2. aIn correlation analysis, severity of AD was quantified by different methods given in parentheses
  3. bmild: SCORAD < 25; severe: SCORAD > 50
  4. cmild: SCORAD < 40; severe: SCORAD ≥ 40
  5. didentified by Rajka Langeland severity score
  6. eTeenagers are defined as minors older than 14
  7. fAges of AD patients are not noted
  8. gonly children show significant increase of FABP4 in AD
  9. hLocal severity score of a measured lesion was presented by the sum of the respective severity scores (0–24) based on the modified scoring scale of each eruption shown in the SCORAD index and clinical features shown by Leung
