3.1 Baseline characteristics
From 167 cases and 66 controls that were recruited for the PreDicta
cohort, a total of 140 asthmatic children (82 males, 58%) and 53
healthy controls (22 males, 42%) were included in this study. The
reason for the exclusion of 27 subjects was insufficient blood samples
for cell culture experiments. The respective number of cases and
controls per study center is: Athens 36/13, Erlangen 22/15, Ghent 20/13,
Lodz 25/4 and Turku 37/8. Mean age at recruitment was 5.3 ± 0.7 in
asthmatic and 5.0 ± 0.8 in healthy children. The majority of asthma
cases additionally suffered from allergic rhinitis (63.5%) and more
than half of them (52.1%) reported atopic dermatitis, while 31.4% had
experienced adverse food reactions.
