  • Variables are adjusted for PA/non-PA status, sex, age, BMI, onset of symptoms, mMRC score, LCQ score and FEV1% of predicted (%).

  • BMI, body mass index; FEV1, forced expiratory volume in 1 s; LCQ, the Leicester Cough Questionnaire; mMRC, modified Medical Research Council; PA, Pseudomonas aeruginosa.
