  1. a: Haplotypes with frequency ≥0.01 were considered.
  2. b: The main effects of haplotypes were in dominant, dominant and additive models for PHF11, DPP10 and HLA-G, respectively.
  3. c: Skin prick test. A positive skin prick test was defined as at least one antigen-induced wheal size >2 mm of the saline control value.
  4. d: Combined asthma status and skin prick test. All cases were asthmatic with a positive skin test result, while all controls were non-asthmatic with a negative skin test result.
  5. e: Airway methacholine challenge test. Negative and positive responses were defined as no PD20 observed and a PD20 observed in the test, respectively.
  6. f: Combined asthma status and methacholine challenge test. All cases were asthmatic with a positive challenge test result, while all controls were non-asthmatic with a negative challenge test result.
  7. *: The associations remained significant (adjusted P ≤ 0.05) after the adjustment for multiple testing.
