Reduction of PNIF during exposure with house dust mite (Der p 1) in the GA2LEN chamber. PNIF development during exposure with house dust mite material. A hash marks a reduction compared to baseline p < 0.001, a dagger a reduction compared to baseline p < 0.01. Outliers are presented as degree sign. PNIF% from the actively exposed group (250 µg/m3) is significantly lower (p < 0.05) than in the placebo group at every associated time of measurement. PNIF% is displayed as medians and boxplots
