Comparing lung function (FEV1), body mass index (BMI) and P. aeruginosa colonisation across socio‐economic categories (SEIFA quintiles) and remoteness (ASGC classification) categories

Medians (M) and interquartile ranges (IQR) reported in brackets, unless otherwise stated. The P‐value is for any statistically significant difference in clinical outcome measures between the two of the groups of SES and Remoteness categories. ASGC, Australian Standard for Geographical Classification; BMI, body mass index; FEV1, forced expiratory volume in 1 s; Ps Aer≥2, two or more positive cultures of Pseudomonas aeruginosa; SEIFA, Socio‐economic index for area (disadvantage); SES, Socio‐economic status.
