Table 2 One-way analysis of variance of error in range of motion determination of a rigidly-fixed 2-vertebrae model (Calibration model 2), acquired from 5 separate screenings on the motion table through 80° in each plane, with 5 consecutive trackings of each image sequence.

From: An objective spinal motion imaging assessment (OSMIA): reliability, accuracy and exposure data
