Figure 3. FeNO versus flow rate in the CHS.
The fractional concentration of exhaled nitric oxide as a function of flow for 1507 CHS participants (left) and for a single participant, under transformations for regression modeling (right). For this participant, the nonLinLog estimates were: CANO = 1.5 ppb, J′awNO = 687.8 pl/s, and DawNO = 4.1 pl·s−1·ppb−1.
