Summary of the number of adults included in the analyses and details regarding missing data. †Cystic fibrosis (CF)‐related diabetes (CFRD) data are collected by the UK CF registry with only a check‐box for ‘CFRD present’. Therefore, if data are not available, it is assumed the person has no CFRD. It is therefore difficult to distinguish missing data from ‘no CFRD’ and hence missing data = 0. ‡Data for pancreatic replacement therapy (PERT) use were obtained. People on PERT were considered ‘pancreatic insufficient’. People not on PERT were considered ‘pancreatic sufficient’. PERT use documented as ‘unknown’ is considered as missing data. § P. aeruginosa status is collected by the UK CF registry with check‐boxes for ‘chronic’ and ‘intermittent’. Therefore, if data are not available, it is assumed the person has no P. aeruginosa. It is therefore difficult to distinguish missing data from ‘no P. aeruginosa’ and hence missing data = 0.
