CI confidence interval, K Cohen’s kappa, vertebral level indicates determination of whether individual vertebrae were unreadable, patient level indicates determination of whether a patient had one or more unreadable vertebral bodies, Younger group had mean age 3.4 years (range 1.3 to 5.2 years), Older group had mean age 9.6 years (range 5.3 to 17.0 years)
