Table 1: Weighted kappa coefficients of each N, I, C, E factor by intra-rater, interrater and CXR versus CT scorings show moderate to substantial level agreement. In the C and I factors of CXR with each other, the relatively high kappa values are seen, whereas in the case of CXR versus CT, the C factors show relatively low value.
