Percentages are given relative to cases of genotype A (n = 60) or B (n = 40). For the following item, radiological signs in chest, only children who had a chest X‐ray have been taken into account. Chronic respiratory disease was measured as binary variable and included bronchopulmonary dysplasia and one case of lung agenesis; GERD, gastroesophageal reflux disease.
Asthma in the family was defined as a history of medical diagnosis of asthma in first‐degree‐relatives. Significant differences are in bold. Differences close to significance are also indicated.
