^aIMD: Index of Multiple Deprivation by Postcode [26].

^bThe Index measures relative deprivation by UK postal code stratifying into 5 quintiles, where 1 is the most affluent and 5 is the most deprived. By entering a postal code, it is possible to obtain an indication of the deprivation level where an individual lives.

^cThe percentage values for deprivation and baseline objective adherence add up to 99% due to rounding issues.

^dMean unadjusted objective adherence over the previous 6 months measured from chipped i-neb nebulizers: high (≥80.0%), moderate (50.1%-79.9%), low (25.1%-50.0%), and very low (≤25.0%) [11,27].
