Intra-observer and inter-observer agreement of CT abnormalities including air trapping and composite CT_BO score

	Inter-observer agreement	Intra-observer agreement
Data are intraclass correlation coefficients. An intraclass correlation coefficient of greater than 0.8 represents good intra-observer and inter-observer agreement.
CT, computed tomography; AT, air (gas) trapping; BO, bronchiolitis obliterans.
CT_AT score	0.86	0.97
CT_BO score	0.78	0.94
Bronchiectasis score	0.84	0.94
Consolidation score	0.78	0.90
Mosaic pattern score	0.68	0.72
Airway wall thickening score	0.61	0.72
Mucus plugging score	0.12	0.39
