Percent PNIF change from baseline. Precent PNIF change from baseline is a more accurate measure of inspiratory flow as PNIF can be quite variable. HDM-allergic participants had significantly decreased precent PNIF change at hours 2 (p < 0.05) and 3 (p < 0.01) compared to healthy controls. * = p < 0.05, ** = p < 0.01
