AIT effectiveness on onset of asthma
Onset of asthma was analysed for non-asthmatic patients at baseline. The probability of asthma medication onset during follow-up was significantly reduced for patients treated within the AIT group compared to controls (OR: 0.77, p = 0.001 (all patients, 5-65 years); OR: 0.78, p = 0.017 (adults, <18-65 years), see Figure 4a). The probability of not being prescribed symptomatic asthma medication was significantly greater for patients treated with AIT compared to the control group (see Figure 4b).
