Table 6 Concordance (in bold text) and discordance for changes between pairs of asthma domains from V1 to V2 for changes equal or greater than the MID (a subset of the PP population). For FeNO, a change of 10 ppb was used (ATS, 2011) whereas for TASX, changes around 0 were used as no MID is available
