Figure 2From: Performance of a new hand-held device for exhaled nitric oxide measurement in adults and childrenDevice agreement. Scatter plots of the mean of three valid FENO measurements using the NIOX vs (A) the mean of three valid FENO measurements, or vs (B) the first valid FENO measurement using the NIOX MINO (n = 61). Repeatability coefficients (ICCs) were (A) 0.97 and (B) 0.98, respectively (p < 0.001 for both).Back to article page
