Time to onset of asthma
When evaluating time to onset of asthma in patients with no asthma at
inclusion, conflicting results were shown. For grass pollen SLIT tablets
the time to onset of asthma was significantly longer compared to the
control group during the 6-years follow-up period (21) while the risk
was significantly increased (hazard ratio (HR): 1.22 (1.12 – 1.32);
p< 0.001) for the AIT group in another study (25). The authors
assumed that a higher frequency of specialist visits in the AIT group
led to more ICD10 coding for asthma. For details see tables S5 and S8 in
supplementary information.
