Fig. 10From: Clinical validation of controlled exposure to house dust mite in the environmental exposure unit (EEU)Symptomatic correlations. TNSS, a subjective measure of AR, and percent PNIF change from baseline, a more objective measure, demonstrated a strong correlation (R2 = 0.8908) indicating accurate reporting of symptoms from participants. A strong correlation between nasal congestion and percent PNIF change from baseline (R2 = 0.9144) also indicate that participants had been properly trained as consistent reporting of symptoms are observedBack to article page
