  1. Kendall’s W coefficient assessed inter-rater agreement among 9 observers, rejecting the null hypothesis (W = 0, random rankings) if P < 0.05 (Friedman’s χ2 test). The strength of agreement between the observers was classified as poor (W < 0.2), fair (0.2 ≤ W < 0.4), moderate (0.4 ≤ W < 0.6), strong (0.6 ≤ W < 0.8), or super (0.8 ≤ W < 1.0). 3D thorax–abdomen-CBCT, 3D cone-beam computed tomography (CBCT) datasets of the thorax and abdomen acquired using CBCT mode.
