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

Inter-observer agreementIntra-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.
