Radiological features and their univariate prediction of bronchoalveolar lavage bacterial burden

	Value	β estimate	se	Adjusted p-value
Traction bronchiectasis extent score	6.7±3.0	0.691	1.750	0.492
Fibrosis extent %	22.0±10.7	1.050	0.921	0.297
Honeycombing extent %	2.6±6.8	−0.028	1.830	0.978
Definite or probable UIP pattern	88.0 (62.4)	−0.597	0.278	0.552
PPFE lobar extent	0.4±0.9	0.414	1.140	0.680

Data are presented as mean±sd or n (%), unless otherwise stated. Traction bronchiectasis scored on an 18-point scale. PPFE scored by number of lobes involved. Univariate regression performed against log transformed 16S rRNA gene copy number. se: standard error; UIP: usual interstitial pneumonia; PPFE: pleuroparenchymal fibroelastosis.
