Recent tobacco exposure and type 2 inflammatory biomarkers in asthma: differential associations with FeNO and eosinophils (A cross-sectional analysis of NHANES 2007-2012).
The relationship between recent tobacco exposure intensity and type 2 inflammatory markers (fractional exhaled nitric oxide [FeNO], eosinophils [EOS]) in asthma, and whether smoking modulates their correlation, remains unclear.
