Correlation between satisfaction with use and screening TNSSs. Too few participants had TNSS 0-3. Of the 834 filter users in week 1, 796 used some form of medication; see Table E1 in this article's Online Repository at for details. The Y-axis depicts percentages. See the text for Spearman's ρ and P values. TNSS, Total nasal symptom score.

Correlation between satisfaction with use and asthma severity. Of the 834 filter users in week 1, 796 used some form of medication; see Table E1 in this article's Online Repository at for details. The Y-axis depicts percentages. Asthma severity was only rated at screening. See the text for Spearman's ρ and P values.
